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 ...

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 ...

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 ...

Ideal diode bridge controller for 9 V to 72 V systems replaces each of the four diodes in a full-wave bridge rectifier with a low loss N-channel MOSFET. The LT4320 from Linear Technology is an ideal ...

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

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 ...

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 ...
