Title: (EN) POWER CONVERSION SYSTEM
(ZH) 电力转换系统
Abstract: front page image
(EN) The present invention provides a power conversion system. The system comprises: an output terminal (TO1) connected to a load (52); a switch (1a) in which a first terminal receives AC power supplied from an AC power source (51) and a second terminal is connected to the output terminal (TO1), and which is turned ON in a first case in which an AC voltage from the AC power source (51) is normal and which is turned OFF in a second case in which an AC voltage (Vi1) from the AC power source (51) is abnormal; a power converter (3) that converts the AC power from the AC power source (51) to DC power and stores the DC power in a storage battery (54) in the first case, and that converts the DC power of the storage battery (54) to AC power and outputs the AC power to the output terminal (TO1) in the second case; and a power source commutation-type inverter (2) that operates synchronously with an AC voltage (Vo1) appearing at the output terminal (TO1), and that converts DC power supplied from a fuel cell (53) to AC power and outputs the AC power to the output terminal (TO1).
(ZH) 本电力转换系统具备:与负载(52)连接的输出端子(TO1);开关(1a),第1端子接受从交流电源(51)供给的交流电力,第2端子与输出端子(TO1)连接,在来自交流电源(51)的交流电压正常的第1情况下被接通,在来自交流电源(51)的交流电压(Vi1)变得异常的第2情况下被断开;电力转换器(3),在第1情况下将来自交流电源(51)的交流电力转换为直流电力并向蓄电池(54)储蓄,在第2情况下将蓄电池(54)的直流电力转换为交流电力并向输出端子(TO1)输出;电源换向式逆变器(2),与在输出端子(TO1)出现的交流电压(Vo1)同步地动作,将从燃料电池(53)供给的直流电力转换为交流电力并向输出端子(TO1)输出。
