Novel MSVPWM to Reduce the Inductor Current Ripple for Z-Source Inverter in Electric Vehicle Applications

Abstract EN

A novel modified space vector pulse width modulation (MSVPWM) strategy for Z-Source inverter is presented.

By rearranging the position of shoot-through states, the frequency of inductor current ripple is kept constant.

Compared with existing MSVPWM strategies, the proposed approach can reduce the maximum inductor current ripple.

So the volume of Z-source network inductor can be designed smaller, which brings the beneficial effect on the miniaturization of the electric vehicle controller.

Theoretical findings in the novel MSVPWM for Z-Source inverter have been verified by experiment results.
