Abstract
The transfer switch (6) supplies the DC voltage supplied from the DC power source section (5), to the commercial electricity system (8) in such a way as to provide the DC voltage with the same polarity as the AC voltage generated by the commercial electricity system (8) according to the control of the commercial voltage monitor section (7) when the absolute value of the voltage of the commercial electricity system (8) is higher than the voltage threshold level. When the absolute value of the AC voltage is lower than the voltage threshold level, the supply of the DC voltage from the DC power source section (5) is interrupted. The generator (2) and the commercial electricity system (8) are isolated from each other by the isolation transformer (4).
