Abstract:
A power conversion system includes: an output terminal connected to a load; a switch configured to be turned on in a first case that an AC voltage from the AC power supply is normal, and to be turned off in a second case that the AC voltage from the AC power supply is abnormal; a power converter configured to convert the AC power from the AC power supply into DC power and store the DC power in a storage battery in the first case, and to convert the DC power in the storage battery into AC power and output the AC power to the output terminal in the second case; and a line-commutated inverter configured to operate in synchronization with an AC voltage appearing at the output terminal, and convert the DC power supplied from a fuel cell into AC power and output the AC power to the output terminal.

Claim (Index 7):
The power conversion system according to  claim 1 , further comprising:\n an abnormality detector configured to detect that the AC voltage from the AC power supply has become abnormal; a current detector configured to detect an instantaneous value of a current flowing through the switch; and a control circuit configured to control the switch and the power converter based on detection results from the abnormality detector and the current detector, wherein the switch does not have self-turn-off capability, in the first case, the switch is set to an ON state, and an alternating current is supplied from the AC power supply to the load through the switch, in the second case, an OFF command signal is provided from the control circuit to the switch and a direct current is output from the power converter to turn off the switch, and furthermore, an alternating current is supplied from the power converter to the load, and assuming that a polarity of a current flowing from the first terminal toward the second terminal of the switch is a positive polarity, and a polarity of a current flowing from the power converter toward the output terminal is a positive polarity, a polarity of the direct current is the same as the polarity of the current flowing through the switch.
