Claim:
1. A driving circuit configured to control at least one switch element comprising: a first voltage generating circuit coupled to a first input voltage and configured to generate a first voltage signal according to a switching period; a second voltage generating circuit coupled to a second input voltage and configured to generate a second voltage signal according to the switching period; and a driving voltage generating circuit electrically coupled with the first voltage generating circuit and the second generating circuit, wherein the driving voltage generating circuit outputs at least one driving voltage signal according to the first voltage signal and the second voltage signal, the at least one driving voltage signal comprises three levels, and at least one level of the levels is lower than a zero level, wherein the switching period is composed of a turn-on duration and a turn-off duration, and the first voltage signal is controlled to be the first input voltage in all the turn-on duration and is controlled to be a first signal in all the turn-off duration, and the second voltage signal is controlled to be the second input voltage in a part of the turn-off duration and is controlled to be a second signal in other time of the switching period.
