Modeling and state feedback control of Z-source inverter

This paper proposes an average model for the Z-source inverter with inductive load without ignoring the inductor resistance in the Z-source network using state space averaging. Based on this model and state feedback control, a controller is designed. This method conducts united control with the shoot through duty ratio and modulation index directly. The simulation results and the experimental results proved that the controller has the characteristic of tracing fast, accurately and small overshoot by conducting united control with the shoot through duty ratio and modulation index directly.
