Self-driven scheme for synchronous rectifier having no body diode
(United States Patent and Trademark Office, 2007-09-04)
A voltage converter uses a component such as a JFET or four-terminal power MOSFET having no body diode and exhibiting no body diode conduction characteristic as a synchronous rectifier to reduce switching losses and body ...
Power converters having output capacitor resonant with autotransformer leakage inductance
(United States Patent and Trademark Office, 2007-08-07)
Power converters having reduced body diode conduction loss, reduced reverse recovery loss and lower switching noise, among other benefits, have a resonant capacitor Cr connected across an unfiltered output. The resonant ...
