Method and Apparatus for Controlling Phase-Shift DC/DC Full-Bridge Converter

摘要

The present invention is a DC-DC full-bridge converter to control the phase shift control device and on its way . will embodiment according to the present invention, the DC-DC pull-in phase shift control unit for controlling the bridge converter, a reference voltage and the direct current-direct current full-bridge converter by comparing the output of the difference value a comparison unit for output; The direct current-direct current full-wave by receiving the standard period of the reference frequency for switching the first square wave converter bridge generator for generating a first square wave; First reflection radio wave generation unit that generates a first half of a radio wave having the inverted phase of the first square wave to receive the first square wave; A phase shift unit for generating a second square-wave filter the phase shift having a value corresponding to the size of a filter input receiving the difference value and the difference value of the reference wave frequency and the same frequency and in case of the filter input file; And provides a phase-shift control apparatus and method for receiving the second rectangular wave by said second generation that includes a second reflection radio wave that generates a second half having a reverse phase of the square wave propagation. ;
