Claim:
1. A circuit comprising: a first electronic switch and a second electronic switch which are electrically coupled in series; a first excitation circuit and a second excitation circuit, for respectively controlling the first and second electronic switches to be turned on and turned off, wherein the first and second excitation circuits are configured to synchronously switch the first and second electronic switches; and a first inductor and a second inductor which are magnetically coupled between each other; wherein the first inductor is electrically coupled between the first excitation circuit and the first electronic switch, for transmitting the switch control signal of the first excitation circuit to the first electronic switch; the second inductor is electrically coupled between the second excitation circuit and the second electronic switch, for transmitting the switch control signal of the second excitation circuit to the second electronic switch; a first clamping circuit, for providing at least two different clamping voltages to the first electronic switch; and a second clamping circuit, for providing at least two different clamping voltages to the second electronic switch, wherein each of the first clamping circuit and the second clamping circuit comprises:
