Power-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.

In Part 1 of this series on audio fundamentals (“Let’s Talk About Some Basics of Audio for Radio”), we discussed audio problems and how to handle audio transformers. Most of today’s studios don’t need ...

Solid state transformers (SSTs) represent a transformative shift in power electronics, replacing conventional electromagnetic transformers with semiconductor-based devices that offer enhanced ...

This project was a sort of challenge: designing an audio amplifier capable of delivering a decent output power with a minimum parts count, without sacrificing quality. The Power Amplifier section ...
