Abstract: front page image
(EN)

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.
