Abstract

An amount of electric power generated by a power supply device is input, an upper-limit current value is calculated using a relationship which varies with operation of the conversion circuit, a lower-limit voltage of the conversion circuit is calculated based on the amount of generated electric power and the upper-limit current value, and control is performed such that a voltage on an output side of the conversion circuit is higher than the lower-limit voltage. Accordingly, even when a voltage conversion device restricts a current output from the conversion circuit, it is possible to curb an influence on an output of the power supply device.
