Abstract
A system includes: an inverter configured to convert DC power from a voltage source to AC power to drive a motor including a plurality of windings, wherein the inverter includes: a first inverter to be connected to a first end of a first winding of the plurality of windings and a first end of a third winding of the plurality of windings; a second inverter to be connected to a first end of a second winding of the plurality of windings and a second end of the first winding of the plurality of windings; and a third inverter to be connected to a second end of the third winding of the plurality of windings and a second end of the second winding of the plurality of windings.
Claims20
A system comprising:
- an inverter configured to convert DC power from a voltage source to AC power to drive a motor including a plurality of windings, wherein the inverter includes:
- a first inverter to be connected to a first end of a first winding of the plurality of windings and a first end of a third winding of the plurality of windings;
- a second inverter to be connected to a first end of a second winding of the plurality of windings and a second end of the first winding of the plurality of windings;
- and
- a third inverter to be connected to a second end of the third winding of the plurality of windings and a second end of the second winding of the plurality of windings.
A system comprising:
- a first inverter to be connected to a first end of a first winding of a plurality of windings of a motor and a first end of a third winding of the plurality of windings;
- a second inverter to be connected to a first end of a second winding of the plurality of windings and a second end of the first winding of the plurality of windings;
- and
- a third inverter to be connected to a second end of the third winding of the plurality of windings and a second end of the second winding of the plurality of windings.
A method comprising:
- operating an inverter circuit to configure a plurality of windings of a motor in an Open Ended Winding configuration, the plurality of windings connectable to a first multi-phase inverter of the inverter circuit and a second multi-phase inverter of the inverter circuit;
- determining that a parameter associated with the motor is beyond a threshold value;
- and
- responsive to determining that the parameter is beyond the threshold value, operating the inverter circuit to configure the plurality of windings in a Delta configuration by connecting a first end of a first winding of the plurality of windings with a first end of a third winding of the plurality of windings, a first end of a second winding of the plurality of windings with a second end of the first winding, and a second end of the third winding with a second end of the second winding.
