双向全桥DC/DC转换器升降压控制系统的设计与实现
Design and realization of Boost-Buck control system for bidirectional full-bridge DC/DC converter
摘要
Abstract
The bidirectional DC/DC converter can realize the high voltage and low voltage bidirectional conversion,and is widely used in the design of various DC voltage⁃stabilized power supply. The nonlinear DC/DC converter is transformed into the linear mathematical model by means of the small signal analysis method for study. The transfer functions of full⁃bridge DC/DC converter in Boost/Buck modes are determined. And then the discrete PID control algorithm is used to analyze the stability of the control system and determine the PID parameters. The compensation network of the converter was designed. The simulation model and prototype experiment were verified,and the results show that the Boost⁃Buck control system of the bidirectional full⁃bridge DC/DC converter is effective.关键词
