Claim 3:
4. A method for controlling a capacity of a compressor, the method comprising:
in response to a demand indicating a first state:
switching, via a control module, a first switch to connect a main winding to a first output of a drive;
switching, via the control module, a second switch to connect a connection point to a second output of the drive; and
switching, via the control module, a third switch to connect a start winding to a third output of the drive,
wherein a motor of a compressor includes the main winding connected at the connection point to the start winding,
wherein the drive is configured to control a speed of the motor;
in response to the demand indicating a second state:
switching, via the control module, the first switch to connect the main winding to a first line voltage;
switching, via the control module, the second switch to connect the connection point to a second line voltage; and
switching, via the control module, the third switch to connect the start winding to a capacitor.
