Abstract:
A driving method for power semiconductor switches in an H-bridge circuit is provided. The method includes: calculating a start time and an end time of a zero level of an output voltage and determining a zero level section based on the start time and end time of the zero level; and driving an upper power semiconductor switch of a first bridge arm and an upper power semiconductor switch of a second bridge arm to be on simultaneously or driving a lower power semiconductor switch of the first bridge arm and a lower power semiconductor switch of the second bridge arm to be on simultaneously in the zero level section.

Claim (Index 11):
The driving method according to  claim 1 , characterized in that the H-bridge circuit further comprises:\n a control circuit for calculating the start time and the end time of the zero level of the output voltage, determining the zero level section based on the start time and the end time, and outputting a first control signal, a second control signal, a third control signal and a fourth control signal in the zero level section; and a plurality of drive circuits for receiving the first control signal, the second control signal, the third control signal and the fourth control signal, respectively, and outputting a first driving signal, a second driving signal, a third driving signal and a fourth driving signal, respectively; wherein the first driving signal is used to drive the upper power semiconductor switch of the first bridge arm to be on or off, the second driving signal is used to drive the lower power semiconductor switch of the second bridge arm to be on or off, the third driving signal is used to drive the upper power semiconductor switch of the second bridge arm to be on or off, and the fourth driving signal is used to drive the lower power semiconductor switch of the first bridge arm to be on or off.
