Abstract
An electronic device comprises: a rectifying unit to rectify an input alternating current voltage; a converter to convert the rectified input alternating-current voltage into a direct-current voltage; an inverter including a plurality of switching elements to convert the direct-current voltage into a three-phase alternating current voltage and outputting the three-phase alternating current voltage to a load; a DC link unit located between the converter and the inverter; and a control unit to control the inverter to convert the direct-current voltage into the three-phase alternating-current voltage according to a pulse width modulation (PWM) control signal. The control unit reduces the speed of a load in response to the detecting of a stop signal with respect to the PWM control signal and controls the load to stop a driving of the load in response to the detecting of a change in the link voltage of the DC link unit.
