Abstract
The power conversion system includes a power conversion circuit, a power conversion control circuit including a charging control mode, and a command value generating part. The charging control mode is a mode in which the output voltage of the power conversion circuit is controlled so that an interconnection inductance receives an interconnection inductance voltage determined by the power supply voltage vector of the AC power supply and the voltage command value vector having a delay phase with respect to the power supply voltage vector and having a magnitude and a phase based on the command value. The command value generating part generates a second command value for operation of the charging control mode when the voltage of the storage battery falls below the over-discharge threshold.
