Applying Ceramic Tech to Achieve High Power Density (Part 1)
June 23, 2023
Capacitors, especially ceramic, are now strongly being considered in electronic design because of their excellent potential to increase efficiency, which ultimately leads to higher power
https://www.electronicdesign.com/technologies/power/article/21268373/electronic-design-applying-ceramic-tech-to-achieve-high-power-density-part-1?utm_source=EG+ED+Analog+%26+Power+Source&utm_medium=email&utm_campaign=CPS230621091&o_eid=7211D2691390C9R&rdx.identpull=omeda|7211D2691390C9R&oly_enc_id=7211D2691390C9R
What you’ll learn:
Comparison of Class I and Class II MLCCs.
The importance of equivalent series resistance.
Why Class I caps are the choice when meeting power-density requirements.
Capacitors and Efficiency in a System Design
In power design, there are three key applications in which capacitors positively impact the efficiency of an electronic system. In each area, the capacitor will have a bit of a different requirement:
In a dc-link, high voltages, high temperatures, high frequencies, and high ripple current will be essential.
With a snubber design, the requirement will be high dv/dt, high voltage, high ripple current, high temperature, and low inductance.
A resonant power converter will need to satisfy high ripple currents, wide operating voltage ranges, as well as capacitance stability maintained over temperature plus dc and ac voltages.
When we combine these above requirements, the design will necessitate a capacitor with very low loss and maintain high ripple-current handling. It must also have the ability to withstand high voltages and handle higher operating temperatures while maintaining a stable capacitance and high mechanical stability. The next section examines capacitor packages that can deliver the above requirements.

How to Choose the Right Protection for Your Circuit

A Practical Introduction to RF/Microwave Balanced Amplifiers and Their Applications

A balanced amplifier is the proper term for a pair of devices operated in quadrature phase and combined to amplify a signal. Quadrature simply means that signals incident upon the devices are 90⁰ out-of-phase with one another. The term “quadrature-combined pair” (often shortened to simply “quad-combined pair”) is perhaps just as common as “balanced amplifier,” and both are as identical as “PTFE” is to “Teflon®.”
This article explains the use of quadrature hybrid splitters and combiners (also often called hybrid couplers) in balanced amplifier configurations and the advantages of combining two amplifier devices in this fashion. Two of the most common applications for the balanced amplifier (quad-combined pair) are described by way of example

Practical Input-Referred Calculations in Precision Systems

What you’ll learn:
Why input-referred calculations are valuable in gaining system insight.
Why combining noise sources referred to input (RTI) and referred to output (RTO) is best to determine system performance.
Defining signal gain.
Applying LTspice and the Signal Chain Noise Analysis tool for simulation and to obtain calculations.
When designing the signal chain for an analog measurement, errors, and noise from different components in the signal chain must be tallied up and used to determine top-level performance. Specifications can be expressed fractionally as a percentage, or if they’re in linear units, they can be output-referred or input-referred. Input-referred calculations tend to cause the most confusion, but they add important insight into system performance.

https://etn.fi/index.php/13-news/15268-galliumnitridi-kutistaa-seuraavaksi-teollisuuden-tehoasteet
Galliumnitridi eli GaN on jo kutistanut älypuhelimien laturit ja parantanut niiden hyötysuhdetta, mutta seuraavaksi vuorossa ovat teollisuuden teholähteet. ROHM on esitellyt uudet tehoasteet EcoGaN-sarjaan. Ne tarkoittavat pienempää kokoa ja pienempiä häviöitä.
Uusissa piireissä on sisäänrakennettu 650 voltin GaN-pohjainen HEMT ja porttiohjain. BM3G0xxMUV-LB-sarja pienentää tehoasteen fyysistä kokoa 99 prosenttia ja tehohäviöitä 55 prosenttia, kun verrataan piipohjaisten MOSFETtien käyttöön. Piirit sopivat ihanteellisesti ensisijaisiin virtalähteisiin teollisuus- ja kuluttajasovelluksissa, kuten palvelimissa ja verkkolaitteissa.
