VERY HIGH FREQUENCY SWITCHING RESONANT SYNCHRONOUS RECTIFICATION

摘要

A VHF switching power converter comprising one or more VHF switching frequency resonant synchronous rectifiers receives an output from an inverter and delivers a DC output to a load. The power converter includes a controller for controlling at least one of the one or more VHF switching frequency resonant synchronous rectifiers based on feedback derived from a waveform of at least one of the rectifiers. The controller controls a phase angle of at least one of the rectifiers with a delay locked loop. The power converter delivers a regulated DC output via adjustment of a phase shift between at least one of the one or more rectifiers and the inverter.
