We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

The other day Linda from Purchasing came to me with a problem: Lou from Operations needed to source a replacement for a shorted diode on a switching power supply. The darned thing was marked with a ...

Everyone loves a full-wave bridge rectifier, but there’s no denying that they aren’t 100% efficient due to the diode voltage drop. Which isn’t to say that with some effort we cannot create an ideal ...

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 ...

Although they are usually limited to only two leads, rectifiers and diodes play an important role in power electronic systems. In 2011, many types of rectifier/diodes were introduced, from bridge ...

Alpha and Omega Semiconductor has announced a family of active diodes which can reduce the 1.2V forward drop of 600V bridge rectifiers. “Both products are self-powered from the AC line and do not ...

In the realm of modern electronics, semiconductor diodes have emerged as fundamental components with diverse applications. One of their pivotal roles lies in the fields of rectification and voltage ...
