Abstract
N (n is a natural number) power converters operate in accordance with a drive signal to generate a power to be supplied to a load. Multi-redundant A/D converters convert an analog detection value from the power converters into digital values. First and second controllers operate in parallel and each generate a drive signal of the power converters using the digital values from the A/D converters. A system selector selects one controller in accordance with an abnormality detection result of the first and second controllers. Each of n output selectors receives the drive signals from both of the first and second controllers and outputs the drive signal from the one controller selected by the system selector to the power converters.
