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 ...

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 ...

Typically, a power supply is comprised of a power transformer, which is then followed by a conventional bridge rectifier. The bridge rectifier is constructed using four diodes that are interconnected ...

Welcome back to this week’s installment of Scope Noob where I’m sharing my experiences learning to use my first oscilloscope. Last week I started out measuring mains frequency using an AC-AC wall wart ...

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 ...

In this installment of the course, we analyze one of the core elements of any power system: the regulated power supply. Starting from the single-phase Graetz bridge rectifier, we will examine the ...

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 ...

Linear Technology announced the availability of a low loss 3-phase ideal diode bridge rectifier reference design, demonstrated on evaluation board DC2465. Linear Technology announced the availability ...

Abstract: A 24-pulse transformer rectifier of multi-electric aircraft design method based on a small-capacity half bridge auxiliary circuit, 12 pulse transformer and 2 sets of rectifier bridge is ...

Linear Technology has launched a diode bridge controller called LT4321 that replaces two diode bridge rectifiers with low-loss N-channel MOSFET bridges to increase the available power and reduce heat ...
