METHOD AND SYSTEM FOR CONTROLLING A PHASE-SHIFT DC/DC FULL-BRIDGE CONVERTER, CAPABLE OF SIMPLIFYING A CIRCUIT

摘要

PURPOSE: A method and system for controlling a phase-shift dc/dc full-bridge converter are provided to simplify control by converting a phase transition filter into an operation reference frequency.;CONSTITUTION: In a method and system for controlling a phase-shift dc/dc full-bridge converter, a comparison unit(102) compares a reference voltage with the output of a DC-DC full bridge converter and outputs a difference value. A first square wave generator(104) receives the period of a reference frequency and generates a first square wave. A first conversion wave generator(106) generates a first conversion wave having the inverse phase of the first square wave. A phase transition filter(108) generates a second square wave having a phase shift value. A second conversion wave generator(110) generates a second conversion wave having an inverse phase of the second square wave.;COPYRIGHT KIPO 2012
