A power generation controller for a vehicle has a rectifier circuit (300) for rectifying the output current of a polyphase ac generator (1) and a regulator (100) for limiting the voltage to a predetermined value. The operation can be restored from the regulated mode reliably. When the battery voltage VB reaches a regulation voltage Vreg at time t1, the phases are regulated. The W-phase is restored at time t2, and then the V-phase is restored at time t3. When the current IW of the W-phase crosses the zero at time t4, the current IU of the unreported U-phase, which is the phase prior to the W-phase, is referenced. If the current IU is positive, the U-phase is restored. |
