Abstract
A control system of an appliance having a motor is provided. The control system includes an inverter circuit configured to provide power to the motor. The inverter circuit has a direct-current (DC) bus. The control system further includes a controller device powered by the DC bus, and a phase fired control device operatively coupled to an input of the inverter circuit. Also, the phase fired control device is configured to control a magnitude of voltage applied to the DC bus based on a phase on angle of the phase fired control device.
