Abstract

A method for controlling an electric compressor according to the present invention comprises the steps of: (I) starting a compressor by applying a power source to an air conditioner; (II) determining whether the compressor is starting normally; and (III) driving the compressor normally if the compressor is starting normally at step (II), or otherwise restarting the compressor if the compressor is not starting normally and then determining again whether the compressor is starting normally. Therefore, at an early stage of starting the compressor, abnormal operations (breakdown, disconnection, overheating and the like) of the compressor are determined by an inverter to determine restart or operation failure of the compressor, thereby improving the reliability of the electric compressor.
