Abstract
A system for driving an inductive load of an appliance is provided. The system includes a direct current (DC) bus of the appliance. The DC bus is coupled to the inductive load of the appliance. The system includes a transistor having a first terminal, a second terminal, and a third terminal. The first terminal is coupled to the inductive load of the appliance. The second terminal is coupled to ground. The system includes a controller coupled to the third terminal of the transistor. The controller is configured to control operation of the transistor to drive the inductive load of the appliance.
Claims19
A system for driving an inductive load of an appliance, the system comprising:
- a direct current (DC) bus of the appliance, the DC bus coupled to the inductive load of the appliance;
- a transistor comprising a first terminal, a second terminal, and a third terminal, the first terminal coupled to the inductive load of the appliance, the second terminal coupled to ground;
- and
- a controller coupled to the third terminal of the transistor, the controller configured to control operation of the transistor to drive the inductive load of the appliance.
A washing machine appliance, comprising:
- a cabinet;
- a wash tub supported in the cabinet;
- a wash basket rotatably mounted in the wash tub and coupled to a motor;
- a solenoid valve configured to regulate a flow of fluid into the wash basket;
- and
- a system for driving the solenoid valve, the system comprising:
- a direct current (DC) bus of the washing machine, the DC coupled to the solenoid valve;
- a transistor comprising a first terminal, a second terminal, and a third terminal, the first terminal coupled to the solenoid valve, the second terminal coupled to ground;
- and
- a controller coupled to the third terminal of the transistor the controller configured to control operation of the transistor to drive the solenoid valve.
