Abstract

See full text

The vehicle generator includes an armature winding, a switching section constituted as a bridge circuit including a plurality of pairs of an upper arm and a lower arm to rectify phase voltages of the armature winding, each of the upper and lower arms being constituted of a switching element parallel-connected with a diode, and a control section for controlling on/off timings of the switching elements. The control section is configured to perform switching operation to switch the switching section between a first operation state where each upper arm is turned off when the phase voltage is higher than a voltage of a vehicle battery, and a second operation state where each upper arm is turned off after the phase voltages becomes lower than the battery voltage, and configured to delay off timings of the switching elements stepwise when the switching section is in the second operation state.
