Patent ID: 11888469
Assignee: MIDEA GROUP CO., LTD.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 9:
10. An electrical appliance comprising:
a power device and a processor connected to the power device,
wherein the power device comprises:
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 connected to the upper bridge arm switch tube through the upper resistor group; and
a second driving circuit, connected to the control input terminal and connected to 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, and
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,
wherein 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.
