Design of Active Damping Control Method for Bidirectional DC-DC Converter
摘要
Abstract
The bidirectional DC-DC converter is affected by load changes during the power conversion process,resulting in poor opera-tional stability.In order to ensure the efficient operation of bidirectional DC-DC converters,an active damping control method for bidi-rectional DC-DC converters is proposed.This method is based on the structural analysis constraints of bidirectional DC-DC converters and utilizes small signal transfer functions to design impedance calculation methods.Based on the damping characteristics of bidirection-al DC-DC converters under constant current load,constant resistance load,and constant power load,an active damping controller is con-structed to achieve active damping control.Experimental verification shows that the proposed method can ensure stable output current fluctuation and small waveform of the controlled bidirectional DC-DC converter,reduce current resonance,and ensure stable operation of the bidirectional DC-DC converter.关键词
