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 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 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 ...

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 ...
