A power system interconnection system includes: a voltage detecting section configured to detect voltage values of a power system line to generate detection voltage values; and a PWM signal generating section configured to generate a PWM signal such that an output voltage follows the detection voltage values. A voltage converting circuit is configured to generate and supply the output voltage to the power system line by performing a pulse-width-modulation control on the power supplied from a power supply based on the PWM signal.
