Claim 7:
8. The power device according to claim 5, wherein the lower driving circuit comprises:
a second input sub-circuit, comprising a first output terminal, a second output terminal, a third output terminal and a fourth output terminal,
wherein:
when the control input terminal is connected to the high level, the first output terminal, the second output terminal, the third output terminal and the fourth output terminal output trigger pulses, and
when the control input terminal is connected to the low level, the first output terminal, the second output terminal and the third output terminal output trigger pulses;

a step-down sub-circuit, configured to step-down a voltage of a power supply to the first voltage range; and
a second voltage output sub-circuit, connected to the second input sub-circuit and the step-down sub-circuit,
wherein:
when the first output terminal, the second output terminal, the third output terminal and the fourth output terminal output trigger pulses, the second voltage output sub-circuit outputs the high/low level signal in the first voltage range, and
when the first output terminal, the second output terminal and the third output terminal output trigger pulses, the second voltage output sub-circuit outputs the high/low level signal in the second voltage range.
