Claim 7:
8. The control apparatus of claim 6, wherein the step-up circuit controller:
adds a reference voltage signal (ML-VREF_BO) from the microcomputer to a voltage (V_HS) of the first battery of the bidirectional insulating DC-DC converter and adds a current value (I_LS) detected by a current sensor in a second voltage stage of the bidirectional insulating DC-DC converter again to input the added signal to a feedback voltage input terminal of the PWM control IC; and
adds a reference current signal (ML-IREF_BO) from the microcomputer to a current value (I_HS) detected by a current sensor in a first voltage stage of the bidirectional insulating DC-DC converter to input the added signal 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-up circuit.
