摘要
Abstract
SWISS rectifier has the characteristics of high output power,adjustable output voltage,easy high-frequency,etc.,which is very suitable for high-power conversion occasions such as high-power charging of electric vehicles,data centers,communication base stations,etc.A design scheme of SWISS rectifier controlled by STM32F334 single chip microcomputer is proposed.The voltage and current PI double closed-loop control strategy is used to achieve accurate control of output voltage,and the control algorithm is designed to realize the function of power factor correction.The hardware circuit scheme of SWISS rectifier is designed,and the method of component parameter calculation and selection is given.A 400 V/1 000 W prototype is made to verify the proposed scheme.The results show that the power factor of the system can reach 0.998 at rated power,the conversion efficiency can reach 97.37%,and the system has a fast response speed.The dynamic adjustment time is less than 70 ms and the voltage overshot is up to 10%at half-load full load.The feasibility of this scheme is verified.关键词
