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 ...

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 ...

Engineers often encounter difficulty when attempting to accurately rectify low-amplitude AC signals using standard diode-based circuits. The primary issue arises from the diode’s forward voltage drop, ...

With Linear Technology’s LT4320 ideal-diode bridge controller, power supply designers can replace each of the four diodes in a conventional full-wave bridge rectifier with a low-loss N-channel MOSFET.

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 ...

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 ...

Linear Technology has released a controller chip that turns four n-mosfets into an active bridge rectifier and cut the expected voltage drop of a bridge from 1.2V to under 100mV, dramatically cutting ...

Rectifiers receive an alternating current (AC) with an average value of zero volts and supply a direct current (DC), single polarity signal with a net value greater than zero volts, a process ...
