电源内阻对双向DC-DC变换器性能的影响
Influence of Source Impedance on Performance of Bidirectional DC-DC Converter
摘要
Abstract
In order to solve the problem of influence on bidirectional DC-DC converter(BDC)by source impedance,this pa-per studies a kind of fundamental topology considering source impedance,establishes an average model for its state space and uses small signal analysis method to get transfer function of the system. Based on bode diagram,it analyzes influence of source impedance on performance of the controller of BDC and presents a kind of design method for controller parameters of BDC considering source impedance. Taking boost mode for an example,it verifies influence of source impedance on vola-tility and transient stability of output voltage of BDC in PSCAD/EMTDC. Results indicate that source impedance has an effect on controlling performance of BDC and it is necessary to consider source impedance for designing control parameters.关键词
