Automatic voltage conversion module including a rectifier for receiving and rectifying a utility AC power, a smoother for smoothing a voltage rectified at the rectifier, a voltage sensor for sensing the voltage from the smoother to determine an amplitude of a supplied power, and a smoothing operation selector for changing operation paths of the rectifier according to result of the determination at the voltage senor, thereby permitting a system to make a smooth and regular operation.
