The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

As [Electronoobs] points out, everything has resistance. So, how hard can it be to make a high-power resistor? In the video below, he examines a commercial power resistor and how to make your own ...

There are a vast array of power supplies on the market, and the variety of resistor applications in those designs broaden the selection dramatically. So, for the purpose of this article, power ...

This three-part series describes how to properly test a DC/DC power supply, and ensure that it works reliably over various operating conditions. This series is intended to provide the designer with a ...

Constant current limiting circuits are commonplace, but sometimes a constant power limiting function is desired instead. This can be because downstream loads, like DC/DC converters, present a constant ...

Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the necessity for special electronic loads, ...
