This lab seeks to illustrate the fundamental operation of uncontrolled rectifier circuits. The waveforms associated with these circuits are visualized using simulation and experimentation. The circuit ...

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 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 ...

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 ...

Full-wave rectifiers with capacitor filters are, without question, the workhorse — and the unsung hero — of the modern electronic world and for the gadgets we have come to enjoy. That being said, it ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...

The lowly diode, a device with only two leads, can nonetheless do many things. Diodes can detect, rectify, suppress, emit light, detect light, change capacitance, emit microwaves and more. This wide ...

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 ...
