Abstract In recent years, the Z-source inverter and the quasi-Z-source inverter are proposed to solve the limitations of the traditional voltage source inverter, which attract a great deal of attention. However, the shortcomings of those two topologies limit their further developments. Here a new type of tapped inductor quasi-Z-source inverter is researched to achieve higher boost ability and smaller capacitor voltage stress. This paper first proposes the generalized DC side small-signal model by using the state-space averaging method, and analyses the impact of the vary in boost network parameters and shoot-through zero state on the system based on the transfer function. The closed-loop regulator of the DC bus voltage is also designed to improve the dynamic performance of the system. Finally, simulations and experiments are carried out to validate the above characteristics.

Key words： Tapped inductor quasi-Z-source inverter small signal model closed-loop control
