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 ...

A diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

A working group of the international PV Quality Assurance Task Force has been undertaking research and testing initiatives aimed at improving the design and long-term reliability of module junction ...

Probably the busiest company in terms of introducing rectifiers/diodes in 2011 was Vishay Intertechnology. Starting in January, the company introduced several types of Trench MOS Barrier Schottky ...

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 ...

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 ...

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 ...

Coherent's Semiconductor Group (CSG) has opened a new commercial applications laboratory to enable customers to see how Coherent's laser diodes might meet their application needs. The new laboratory ...
