Beschreibung
Zusammenfassung:	A main rectifying/smoothing circuit is connected to one end of a secondary winding of a transformer and a plurality of rectifying/smoothing circuits are connected to a plurality of central taps of the secondary winding. The rectifying/smoothing circuits are each equipped with a switch. In a preliminary driving period, a DSP, which controls the switches, reads forward drop voltages of first to third diode loads and sets feedback gains corresponding to the forward drop voltages. The DSP controls the switches based on the set feedback gains and begins rated driving.
