Abstract：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 of 1st, 2nd,…, (n-1)th input sources and the insufficient load power of nth source supplements. The simulation and experimental results of the 1 000V·A DC-AC full-bridge multi-input inverter have shown that the proposed converter has 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.
