Abstract
A power supply system includes a plurality of AC output converters connected in parallel for supplying electric power to an AC load. Each of the plurality of AC output converters includes an output impedance connected to the AC load, a PWM converter configured to convert DC power into AC power, and a controller configured to output a voltage command value to the PWM converter. The controller includes a vector adder configured to perform vector addition of a part of a voltage drop occurring due to a current flowing through the output impedance and a voltage command value of the AC load, and a converter configured to output a voltage command value to the PWM converter based on a vector sum obtained through the vector addition.
