Title: POWER SUPPLY SYSTEM
Abstract:
This power supply system is provided with a plurality of AC output converters that are connected in parallel and that supply power to an AC load. Each of the AC output converters includes: output impedance that is connected to the AC load; a PWM converter that converts DC power into AC power; and a control device that outputs a voltage command value to the PWM converter. The control device includes: a vector adder that performs vector addition on a portion of a voltage drop caused by a current flowing through the output impedance and the voltage command value of the AC load; and a converter that outputs the voltage command value to the PWM converter on the basis of the vector sum obtained through vector addition.
