Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...

Here’s a handy little current source that’s often used to control the current flowing through a load. Find the equation that defines the i-Load current and account for non-ideal sources. The i-Load ...

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 ...
