Bridge rectifier circuit
A bridge rectifier circuit, which takes control of a current flowing through an armature winding of a motor-generator and a battery, includes rectifier elements each made of a MOSFET; phase current detection means that detect the amount and the direction of current flowing between the drain and the source of the FET; and a control means that takes on/off control of the FET by applying a control voltage between the gate and the source thereof; wherein when the phase current detection means detect a reverse current flowing through the FET exceeding a first predetermined value, the control means applies a control voltage between the gate and the source of the FET so as to turn on the FET.
