High Voltage: Dealing with Partial Discharge
Aug. 29, 2023

Galvanic Isolation Made Easy
Nov. 17, 2020
Sponsored by Texas Instruments: Separating power supplies is a crucial factor in modern equipment designs, especially in terms of safety. New analog ICs help simplify meeting those isolated current- and voltage-sensing needs.
Lou Frenzel
https://www.electronicdesign.com/technologies/power/whitepaper/21148000/galvanic-isolation-made-easy?utm_source=EG+ED+Analog+%26+Power+Source&utm_medium=email&utm_campaign=CPS230817080&o_eid=7211D2691390C9R&rdx.identpull=omeda|7211D2691390C9R&oly_enc_id=7211D2691390C9R
Galvanic isolation is the process of designing equipment or systems with separate power supplies so that the two don’t exchange power or interact in any way. The idea is to keep the dc power (and/or ac power) separate and independent. One electrical power system should not affect the other. At the same time, it’s usually necessary to transport monitoring signals and control data between the two in a fully isolated way.
Power isolation is achieved by keeping the two physical sections well apart. And that’s usually implemented by NOT connecting the ground connections of the two systems. This eliminates ground loops and reduces or at least minimizes any noise transference. When both high- and low-voltage subsystems are used, such physical and ground isolation also helps to protect users and service techs from shock, low-voltage circuits from high voltage, and in some cases, protects against lightning.
A wide range of methods are used to implement galvanic isolation. Perhaps the oldest and still most effective is the transformer. It operates by allowing its two windings to transfer data, messages, and codes by way of magnetic fields between the primary and secondary windings. There’s no direct current flow between the primary and secondary windings.
Optocouplers or optoisolators are another near ideal device for transferring data at reasonable speed. A voltage data stream drives an LED inside the optoisolator package. A phototransistor captures the light a few millimeters away. The transistor output is fully isolated from the input. Isolation is very complete.
One of the best isolation techniques is to use capacitors. They block dc but pass ac, making them and their variants extremely efficient. Other devices involved in creating galvanic isolation are special components like Hall-effect sensors and even mechanical relays.
Modern Galvanic Isolation
The best way to provide needed galvanic isolation these days is to utilize products designed particularly for that purpose. Examples include the special amplifiers and analog-to-digital converters (ADCs) used to send isolated current- and voltage-sensing data when the system needs it.
Differential amplifiers monitor the voltage across a sensing resistor to provide a current reading. Usually two power supplies are required in this application (Fig. 2, left). However, having a second supply makes the product larger, heavier, and more expensive.
Texas Instruments has developed a line of single-supply amplifiers and ADCs to overcome that issue. The AMC3301 isolated amplifier (Fig. 2, right) includes a fully integrated dc-dc converter to deliver the second supply voltage. Isolation is provided by capacitive coupling inside the IC. The AMC3301 meets the high-voltage isolation safety rules for UL 1577 certification up to 4250 V rms and DIN VDEV 0884-11 for up to 6,000 V peak.
Two types of isolation devices can be used to provide the isolated measurement and control data—an isolated amplifier and an isolated modulator. Both are single-supply types, and each contains an internal delta-sigma (ΔΣ) ADC.
The monitored analog signal is sent to the chip, amplified, and then digitized by the ADC. The ADC generates a serial bit stream that passes through an on-chip capacitive isolation barrier. This serial bit stream is subsequently sent to a low-pass filter that produces a voltage proportional to the input. At that point, the recovered dc signal may be digitized again in another ADC, perhaps one in the usual system microcontroller,
An option is an isolated modulator like TI’s AMC1305/06. It takes the current or voltage signal being monitored and amplifies it before digitizing it in a faster ΔΣ ADC. The ADC sends its signal over the internal capacitive isolation barrier to the output. This signal is a series of bits representing the voltage inside the device. An external low-pass filter generates a proportional analog signal that may again be digitized for digital signal processing.
While both isolated amplifiers and modulators do provide good performance, the isolation modulators are generally a better alternative. They have superior signal-to- noise performance, greater accuracy, and lower latency.

Is This the End for the Optocoupler in High-Voltage Isolation?
Sept. 19, 2023
https://www.electronicdesign.com/technologies/power/article/21273990/electronic-design-is-this-the-end-for-the-optocoupler-in-highvoltage-isolation?utm_source=EG+ED+Analog+%26+Power+Source&utm_medium=email&utm_campaign=CPS230914119&o_eid=7211D2691390C9R&rdx.identpull=omeda|7211D2691390C9R&oly_enc_id=7211D2691390C9R
Learn more about TI’s new family of opto-emulators and how they differ from traditional optocouplers.
What you’ll learn
The importance of signal isolation in high-voltage design
The difference between optocouplers and opto-emulators
Details on TI’s silicon dioxide (SiO2) isolation technology
Isolation is invaluable in everything from industrial motor drives on factory floors to electric-vehicle (EV) traction inverters, where it’s necessary to deter dangerous high voltages from entering the more fragile parts of the system.
Optocouplers have been the “go-to” for isolating analog and high-speed digital signals traveling through power supplies and systems for decades, enhancing reliability and safety in the process, said Tsedeniya Abraham, VP and GM of interface products at TI. She added that while they can facilitate the safe transfer of signals and data from the input stage in a power supply and its output terminals or load, the optocoupler is no longer cutting it as power levels rise in the automotive and industrial sectors.
TI is trying to bring the optocoupler into the future with a new family of what it calls “opto-emulators.” Based on its silicon-dioxide (SiO2) isolation technology, the parts are pin-to-pin alternatives to optocouplers for high-voltage signal isolation. And the company claims they bring better power efficiency, signal integrity, and reliability to the table while extending the lifespan of high-voltage industrial and automotive systems.
TI, which is entering the optocoupler market for the first time with its digital-output ISOM8710 and ISOM8711 and the analog-output ISOM8110, said they can slot into virtually any high-voltage power system where optocouplers are used today.
That includes EV traction inverters and onboard chargers (OBCs), industrial motor drives, programmable logic controllers (PLCs) and other factory automation and control systems, as well as lighting systems and solar, wind, or other renewable-energy inverters for the grid.
“These are drop-in replacements for optocouplers that are reliable and robust, and, at the same time, they have better signal performance over a wider range of temperatures,” said Azhar Mohammad, TI’s head of isolation product management.
“Wherever high voltage is in play, isolation will go hand in hand,” said TI’s Mohammad.
Oftentimes, designers looking to add high-voltage signal isolation to a system will turn to optocouplers. They’re typically used to isolate the high- and low-voltage zones of a system or eliminate the electrical noise coupling from signals traveling through a power supply or other type of system
In general, optocouplers can be applied to everything from input and output switching of the processor in a system to DC and AC power control. They’re also useful for regulating the power supply’s output voltage. When output voltage deviates either due to line and/or load changes, the power supply’s MCU adjusts the PWM output. In turn, the PWM directs the power MOSFET on the primary side via the optocoupler.
Can the Opto-Emulator Take the Optocoupler’s Place?
Optocouplers are constantly improving. But as higher voltages and power levels become the standard in industrial and automotive systems, TI contends that existing optocouplers aren’t evolving fast enough.
Voltage levels are rising, including in EVs, where high-voltage battery packs are becoming the rule rather than the exception. But according to TI, high-voltage reliability and long-term robustness are areas where traditional optocouplers are lacking. They also typically consume more power due to variations over time in how efficiently they can transfer current, and they are falling behind in bandwidth, which affects response times to load transients.
TI explained that it uses semiconductor technologies in its opto-emulators to recreate how optocouplers work. The isolation barrier itself is based on TI’s proprietary SiO2 isolation technology, which is said to deliver more robust insulation properties compared to the usual forms of isolation inside optocouplers.
As a result, TI claims the opto-emulators are more robust in the long run than standard optocouplers. The optocoupler’s insides tend to degrade over time. Thus, its performance erodes due to aging, too, which can be detrimental to automotive- and industrial-grade power supplies that are designed to remain in use for decades while being subject to harsh environmental conditions. As a result, optocouplers require up-front overdesign to counteract the aging of the LED.
Even the isolation barrier inside the optocoupler can degrade over time due to the stress of constant exposure to high voltages. In contrast, TI touted the very high dielectric strength of its silicon-based isolation technology, giving the opto-emulators more robust isolation properties that can last 40 years or more without deteriorating.
One of its other key characteristics is its resistance to moisture. According to TI, SiO2 doesn’t degrade when exposed to ambient moisture for extended periods of time, improving its robustness in the long run.
Inside the Opto-Emulator: Robust Isolation Ratings
TI said the first chips in the new opto-emulator family are footprint-compatible with many of the most popular optocouplers on the market, making them easy to integrate into existing designs.
With operating voltages of up to 500 V RMS, the opto-emulators maintain a maximum isolation rating of up to 3.75 kV RMS. The components can also withstand voltage surges of up to 10 kV.
TI said the ISOM8710 features a minimum CMTI of ±85 kV/μs, while it typically supports 150 kV/ μs, which helps both sides of a high-voltage power supply operate within specifications even when exposed to fast transient events.
Furthermore, the chips have a very short propagation delay and reduced pulse-width distortion (PWD).
TI said the opto-emulators are suited for high-speed systems, as the chips support stable performance over temperature and aging. They can deliver data rates of up to 25 Mb/s and can output 3.3- and 5-V signals with different digital logic outputs: CMOS-compatible output (ISOM8710) or open drain output (ISOM8711). The ISOM8110, which outputs analog signals, has a high bandwidth of 680 kHz.
TI said opto-emulators consume up to 80% less power at a component level.
“It ultimately depends on the system design and the voltages being used, but essentially, the more devices that you use to replace optocouplers, the more power savings you will see compared with optocouplers,” said Mohammad.
As a result, one potential application for the opto-emulators is output regulation on the secondary or high-voltage side of a switched-mode power-supply (SMPS) design based on the flyback converter topology, one of the most widely used power topologies
A Pin-to-Pin Replacement for the Optocoupler?
Besides performance, TI said it also focused on ease of use when it was working on the opto-emulators.
It offers the new opto-emulators in the same packaging footprints as existing optocouplers. According to the company, using them requires no alterations to the system design or the positioning of components on a PCB.

Improving accuracy and precision, and minimizing system noise is a common challenge for engineers designing a power supply for noise-sensitive systems for medical applications, test and measurement, and wireless infrastructure that use clocks, data converters or amplifiers. Although the term “noise” can mean different things to different people, in this article I’ll define noise as low-frequency thermal noise generated by resistors and transistors in the circuit. You can identify noise through a spectral noise-density curve in microvolts per square-root hertz, and as integrated output noise in root-mean-square microvolts, typically over a specific range from 10 Hz to 100 kHz. Noise in the power supply can degrade the analog-to-digital converter’s performance and introduce clock jitter.

Buck Converter Takes 8V To 100V
https://hackaday.com/2023/09/17/buck-converter-has-tremendous-range/
For those living before the invention of the transistor, the modern world must appear almost magical. Computers are everywhere now and are much more reliable, but there are other less obvious changes as well. Someone from that time would have needed a huge clunky machine like a motor-generator set to convert DC voltages, but we can do it with ease using a few integrated circuits. This one can take a huge range of input voltages to output a constant 5V.
The buck converter was designed by [hesam.moshiri] using a MP9486 chip. While it is possible to use a multipurpose microcontroller like something from Atmel to perform the switching operation needed for DC-DC converters, using a purpose-built chip saves a lot of headache.

https://hackaday.com/2023/09/17/buck-converter-has-tremendous-range/
DC-to-DC buck converters are utilized ubiquitously in electronic devices. Three major types of non-isolated DC-to-DC converters are introduced: Buck, Boost, and Buck-Boost. The most frequently employed type is the Buck converter. In this article/video, I introduce a compact buck converter board, capable of accepting input voltages ranging from 8V to 95V and handling 5V-1A at the output
