【摘 要】为满足微电网孤岛模式下对双向变流器动态响应快的要求,针对户用交流高频链双向储能变流器的双环控制展开研究。通过分析交流高频链的开环模型,提出将交流高频链同电感电流内环/电压外环的双环控制相结合,并利用极点配置设计内外环控制器参数。最后,通过仿真模型和试验样机对所采用的双环控制策略进行验证。仿真和试验结果证明,采用基于极点配置的双环控制策略能有效改善交流高频链双向储能变流器的稳态和动态性能。

Abstract： In order to meet the requirement of fast dynamic response to

bidirectional converter in islanding mode,the double-loop control of AC

high frequency linked bidirectional converter was studied.By analyzing the open-loop model of AC high-frequency link,it was proposed to combine

the AC high-frequency link with the double-loop control of inductance

current inner loop and voltage outer loop,and the inner and outer loop
