Self-driven circuit for synchronous rectifier DC/DC converter
(United States Patent and Trademark Office, 2006-03-21)
A power converter having a primary circuit (e.g. full bridge) and a secondary circuit (e.g. current doubler) has switches in the secondary circuit that are controlled by a drive circuit. The drive circuit is connected to ...
Two-stage voltage regulators with adjustable intermediate bus voltage, adjustable switching frequency, and adjustable number of active phases
(United States Patent and Trademark Office, 2006-07-04)
A two-stage power converter that dynamically adjusts to output current requirements includes a first stage regulator that provides power to a second stage regulator. The first stage can be a buck converter, and the second ...
Quasi-resonant DC-DC converters with reduced body diode loss
(United States Patent and Trademark Office, 2006-01-24)
Buck converters having a resonant inductor Lr, resonant capacitor Cr, and synchronous switch Q3 that together provide reduced switching loss and soft switching. In operation, the resonant inductor Lr is charged during a ...
