Abstract:The paper focus on the problem of higher THD of inverter, a novel seven level single-phase inverter topology was proposed. A seven-level inverter was realized based on adjusting the DC bus voltage which is controlled by switch the Mosfets. Compared with the traditional seven-level inverter, the topology used fewer switched and reduces the voltage stress of some of switches to xx switching loss and improve the stability of the system effectively, meanwhile the wide range of voltage gain of the system can higher up to 3~30 times of input DC voltage, it's especially use for inverter with lower DC input. Finally, the paper validates the feasibility of the system by simulation mode of PSIM.
