1. A rectifier circuit, comprising:
a switch circuit having a plurality of switches and configured to rectify an alternating-current voltage of an alternating-current voltage line, all of the plurality of switches being bidirectional switches, wherein a dead time when all of the bidirectional switches are turned off is present; and
a surge suppression circuit connected to the alternating-current voltage line and including a first inductor and a first capacitor configured to continuously accumulate energy output from the first inductor without saturation during a period of the dead time.
