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 ...

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 ...

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 ...

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 ...

The IRF6811 and IRF6894 DirectFET power MOSFETs target use in 12V-input, synchronous-buck applications, including next-generation servers, desktops, and notebooks. The IRF6811 features a typical drain ...

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 ...

International Rectifier has expanded its portfolio of RAD-Hardä Logic Level gate drive MOSFETs with the introduction of 60 V, 100 V and 250 V MOSFETs for switch mode power supplies (SMPS), satellite ...

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 ...
