CPC H03K 17/6871 (2013.01) [H02M 1/088 (2013.01); H02M 3/158 (2013.01); H02M 7/003 (2013.01); H02M 7/53871 (2013.01); H03K 17/693 (2013.01)] | 18 Claims |
1. A power device comprising:
a control input terminal;
an upper bridge arm switch tube and a lower bridge arm switch tube;
an upper resistor group and a lower resistor group;
a first driving circuit, connected to the control input terminal and the upper bridge arm switch tube through the upper resistor group; and
a second driving circuit, connected to the control input terminal and the lower bridge arm switch tube through the lower resistor group,
wherein:
the control input terminal is connectable to a high level or a low level,
when the control input terminal is connected to the high level, the first driving circuit and the second driving circuit output a high/low level signal in a first voltage range,
when the control input terminal is connected to the low level, the first driving circuit and the second driving circuit output a high/low level signal in a second voltage range, and
the first voltage range is different from the second voltage range, and
wherein:
when the upper bridge arm switch tube and the lower bridge arm switch tube each comprise a GaN device, a high level is input to the control input terminal, and
when the upper bridge arm switch tube and the lower bridge arm switch tube each comprise a Si device, a low level is input to the control input terminal.
