Abstract
A single-stage three-phase high-gain boost-type three-port integrated inverter includes a center-tapped energy storage inductor, a three-phase inverter bridge and a three-phase filter, which are successively connected in cascade. A drain terminal and a source terminal of the energy storage switch are respectively connected to the center tap of the energy storage inductor and the negative electrode of an input DC power source. A battery charge/discharge switch unit is connected between a positive electrode of the input DC power source, a positive electrode of a battery and two ends of the center-tapped energy storage inductor. The inverter has three ports, an input port, an output port, and an energy storage port. The inverter has three modes which are the input power supply supplies power to the output load and the battery, the input power supply and battery supply power to the output load, and the battery supplies power to the load.
