摘　　要：提出多绕组同时供电直流变换器型多输入逆变器电路结构与拓扑族及其主从功率能量管理移相控制策略,对其控制策略、稳态原理特性和主要电路参数设计准则等关键技术进行深入分析研究,获得重要结论。该电路结构是由Boost型多绕组直流变换器和Buck型逆变器两级级联而成,主从功率能量管理是指第1,2,…,n-1路输入源输出最大功率,第n路输入源补足负载所需的功率。1 000V·A DC-AC全桥式多输入逆变器的仿真和实验结果表明,该变换器具有高频电气隔离、电压匹配能力强、功率密度高、多路输入源可同时向负载供电、占空比调节范围宽、多模态平滑切换等优点。This paper presents the circuit configuration,topological family and the master-slave power energy management phase-shifting control strategy for multi-winding simultaneously-supplying DC-DC converter mode multi-input inverter.Meanwhile,this paper also investigates the control strategy,steady principle and design criteria of the main circuit parameters.This circuit configuration is composed of a Boost multi-winding DC-DC converter and a cascaded Buck type inverter,while the master-slave power energy management means the maximum powers of1st,2nd,…,(n?1)th input sources and the insufficient load power of nth source supplements.The simulation and experimental results of the1000V·A DC-AC full-bridge multi-input inverter have shown that the proposed converterhas the advantages such as input/output isolation and input/input isolation,strong voltage matching ability,high power density,simultaneous power supply by multiple input sources in a high-frequency switching cycle,wide regulating range of duty cycle,and smooth transition among different operating modes,etc.
