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 ...

Astrodyne TDI introduced a rugged and portable test rectifier. The Lightweight Test Rectifier (LTR), part of the Defender product line, is designed to test impressed current cathodic protection (ICCP) ...

Many years ago I was using 2N918 transistors in an RF application. That transistor comes in a size TO-72 package, which has four leads, one each for the collector, the emitter, the base and the ...

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 ...

The most demanding component in terms of high-frequency operation on an RF-ID tag is the rectifying device: this device needs to be able to charge a storage capacitor providing quasi-d.c. power supply ...

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 ...
