Z-source network inverter circuit, method and device and Z-source network inverter

The invention discloses a Z-source network inverter circuit, method and device and a Z-source network inverter. The Z-source network inverter circuit comprises a power supply input module used for providing a DC power supply, an X-type impedance network whose two input ends are connected with the power supply input module, a first IPM module used for supplying power to a first load, a second IPM module used for supplying power to a second load, and a power supply conversion module used for supplying power to a third load. The first IPM module is connected to the two output ends of the X-type impedance network, the second IPM module is connected to the two input ends or the two output ends of the X-type impedance network, and the power supply conversion module is connected to the two input ends or the two output ends of the X-type impedance network. The embodiment of the invention can provide power for different loads at the same time, simplify the circuit structure and reduce the circuit cost.
