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 ...

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 ...

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 ...

Last week we covered diodes, specifically thermionic and PN junction diodes. But oh, there are more; and they’re special! One of the the most commonly used ‘specialty’ diode would have to be the metal ...

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 ...

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 ...

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...

Vishay Intertechnology VSH unveiled two new 1200 V FRED Pt Hyperfast rectifiers, namely VS-E7MH0112-M3 and VS-E7MH0112HM3c, in its Gen 7 platform. Notably, both devices come in an SMA (DO-214AC) ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...
