Abstract
A bridge rectifier circuit has first to fourth diode groups which are bridge-connected and each include a main diode and sub-diodes being enabled to be respectively connected in parallel to the main diode, first and second input terminals to which AC power is supplied, a first output terminal connected to the first input terminal via the first diode group and connected to the second input terminal via the second diode group, a second output terminal connected to the first input terminal via the third diode group and connected to the second input terminal via the fourth diode group, and a control circuit configured to detect a current flowing through at least one diode group and increases the number of sub-diodes connected in parallel to the main diode of the diode group through which the detected current flows in accordance with an increase in the detected current.
