Many loads are mainly resistive; thus, they’re rated in watts (i.e., true power). Simply stated, these loads have a very small reactive component, which means an apparent power rating (VA) would not ...

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, ...

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 ...
