双向H4桥变换器的统一控制
Unified Control of Bidirectional H4 Bridge Converter
摘要
Abstract
Aimed at the time-delay oscillation of a bidirectional H4 bridge converter in a single-phase energy storage inverter,a unified control method for the bidirectional H4 bridge converter is proposed.In this method,a voltage regulator is used to control the power flow of the converter,and a set of bidirectional feasible control parameters are derived based on the power balance theory.At the same time,in order to realize AC current tracking input voltage without static error and increase the stability,the current inner-loop adopts a quasi proportional resonance controller,and a second-order generalized integrator is used to design a phase-locked loop.PSIM simulation and experimental results show that the proposed method can realize seamless switching between the rectification and active inverter modes,and it also has a good effect in the startup and switching between different modes.Therefore,it can realize stable control of the bidirectional AC-DC bridge converter in a single-phase photovoltaic energy storage system and obtain a good dynamic performance.关键词
