摘要：

A feedforward compensator applied in Z-source inverter ASD system has been presented. With this technique a constant peak dc-link voltage can be achieved with an excellent transient performance which enhances the rejection of input voltage ripple, and have good ride-through for voltage-sags. The effect of six pulse input voltage ripple which result from front-end diode rectifier has been described in detail, and the compensator is designed. The Z-source inverter ASD system with feedforward compensator has rapid transient response and good ride-through for voltage sag. It is very suitable for practical application due to its simplified controller design. The proposed technique was verified on a 10-kW prototype. The experimental and simulation results verified the theory very well.
