Comparison of a 5W laser, 10W, and 20W diode laser. All these machines have their pros and their cons, but this is a quick ...

Power MOSFETs are well known for superior switching speed, and they require very little gate drive power because of the insulated gate. In these respects, power MOSFETs approach the characteristics of ...

This document presents switching power supplies in focus. It tackles about the types, uses, functions and advantages of switching power supplies compared to the other ones. It also discusses some ...

A major cause of losses in a conventional power supply using a 50/60-Hz transformer is the bridge rectifier. This article shows how to build a “greener” rectifier, substantially reducing losses by ...

We always enjoy [w2aew’s] videos, and his latest on zener diodes is no exception. In it, he asserts that all Zener diodes are not created equal. Why? You’ll have to watch the video below to find out.

Find a downloadable version of this story in pdf format at the end of the story. Silicon Schottky diodes are used in power applications because of their low forward voltage drop, which allows lower ...
