Claim 5:
6. A control apparatus for a bidirectional insulating DC-DC converter comprising:
a step-down circuit including an active clamp forward converter circuit and configured to step down a voltage applied from a first battery and output the stepped-down voltage to a second battery, a discharge voltage of the first battery being relatively higher than that of the second battery, and a step-up circuit including an active clamp flyback converter circuit, connected in parallel to the step-down circuit and configured to step up a voltage applied from the second battery and output the stepped-up voltage to the first battery, the control apparatus comprising:
a step-down circuit controller configured to control the step-down circuit in a peak current mode control method; and
a step-up circuit controller configured to control the step-up circuit in an average current mode control method,
wherein the step-down circuit controller comprises a pulse width modulation (PWM) control integrated circuit (IC) configured to output a PWM signal for PWM switching control of a semiconductor switch element of the step-down circuit, and a microcomputer configured to provide a control signal to the PWM control IC, and
the step-up circuit controller comprises a PWM control IC configured to output a PWM signal for PWM switching control of a semiconductor switch element of the step-down circuit, and a microcomputer configured to provide a control signal to the PWM control IC.
