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 ...

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.

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 ...

Not that this happens often, but what do you do when faced with a repair where you don’t know the power source but you do know you have to drive LED backlighting? When faced with this dilemma [Eric ...

Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

Snubbers play an important role in switch-mode power supplies. To understand use of the snubber, we have to look at the performance of a switch-mode power supply. Fig. 1. RCD and R2CD snubbers for ON ...
