Abstract
A controller of a power supply system includes a memory configured to store a self-inductance and a mutual inductance of two reactors included in a boost converter; and a processor configured to determine a present operating state of the boost converter, based on a ratio of an input voltage into the boost converter to an output voltage therefrom, a duty ratio applied to switching elements of the boost converter, the self-inductance, and the mutual inductance, the present operating state being one of operating states among which the waveform of a reactor current differs; and measure an average of the reactor current in a predetermined switching period of the switching elements, based on the input voltage, the output voltage, and the duty ratio, in accordance with the waveform of the reactor current corresponding to the present operating state of the boost converter.
