The losses in a bridge rectifier can easily become significant when low voltages are being rectified. The voltage drop across the bridge is a good 1.5 V, which is a hefty 25% with an input voltage of ...

The switching speed of a power MOSFET charge-controlled device depends on the speed with which an associated gate driver circuit can charge its input capacitance. For the last 20 years, many excellent ...

After discussing the three transistor high-side buck p-mosfet driver (a recognised circuit and not mine) with some of EW’s sage commenters, I wondered once again if I could design something similar ...

There was this fellow, Rudy Severns, who many years ago went on a speaking tour for International Rectifier to discuss “Hexfets,” their power MOSFETs, when that product line was still new. If memory ...

International Rectifier’s IRF7835PbF and IRF7836PbF are 30-V synchronous buck HEXFET MOSFETs intended for dc-dc synchronous point-of-load (POL) converters. The SO-8 MOSFETs are well suited for systems ...

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 ...

Couldn’t resist simulating the possible Cuk synchronous rectifier mosfet drive circuit. And the results are not good (but scroll down for a better circuit:) The voltage across the capacitor pretending ...

Alex Lidow, former CEO of International Rectifier and CEO of Efficient Power Conversion, is one of the few individuals to have pioneered two revolutionary power semiconductor technologies – the ...
