The field winding 50 is electrically connected onto a current path between a battery B and a power supply line 107. A controller 100 sets a target value of a voltage step-up current outputted from a voltage step-up converter 120 in accordance with a deviation between a voltage command value and a detection voltage from a voltage sensor 130, and sets a target value of a field increase current supplied to the field winding 50 in a direction of strengthening a field in accordance with a deviation between the current command value and a detection value from a current sensor 112. When the voltage step-up current and the target value of the field increase current are synthesized to generate a current command value, the controller 100 switching-controls switching elements Q1-Q3 so that the detection current from the current sensor 112 may match the current command value.
