Claim 6:
7. The control apparatus of claim 6, wherein the step-down circuit controller: converts a current value of a first voltage stage of the step-down circuit into a voltage to input a current (IHSBU) detected in a current transformer to be detected to a current sense amplifier input terminal of the PWM control IC; adds a reference voltage signal (ML-VREF_BU) from the microcomputer to a voltage of the second battery of the bidirectional insulating DC-DC converter to generate an added voltage, and inputs the added voltage to a feedback voltage input terminal of the PWM control IC; and adds a reference current signal (ML-IREFBU) from the microcomputer to a current value (ILS) detected in a current sensor in a second voltage stage of the bidirectional insulating DC-DC converter to input the added current to a threshold setting terminal of the PWM control IC so that the PWM control IC generates the PWM signal for controlling the semiconductor element of the step-down circuit.
