Abstract
In a DC/DC converter having a plurality of DC/DC converters, to prevent faults in the circuit and the circuit elements constituting it even when the balance of current limiting operation among the individual DC/DC converters is disturbed due to individual and temperature-related variations in the characteristics of the circuit elements, the output currents of the individual DC/DC converters are detected and added together, and are limited individually so that their sum does not exceed a predetermined level of current.
