Abstract
A power supply control device according to one or more embodiments may be provided, in which a power conversion device has a configuration in which a resonant circuit is provided on an output side of a matrix converter using switching circuits including snubber elements so as to perform AC-AC conversion of output from a multi-phase AC power supply. The power conversion device is controlled to make an amplitude of an output current, a phase of the output current and an instantaneous reactive power as close to a control target as possible. The amplitude and the phase of the output current and the instantaneous reactive power are derived based on: an input voltage and a phase of a multi-phase current input to the power conversion device; and characteristics of the resonant circuit.
