Abstract
A limit value of an output current of power converter is defined as a first current value when a voltage at both ends of capacitor is higher than a voltage at both ends of battery, and a limit value of the output current thereof is defined as a second current value when the voltages are substantially equal to each other, the first current value is set to be smaller than the second current value. Thus, when a voltage at both ends of capacitor and a voltage at both ends of battery are substantially equal, heat is hardly generated. The limit value of the output current is set to a maximum current consumed by load. When a voltage at both ends of capacitor is higher than a voltage at both ends of battery, the limit value of the output current is set to be smaller than the second current value, and thereby heat generation is suppressed. Thus, the size of the heat dissipating components can be reduced, and a power supply system whose entire size can be minimized can be provided.
