POWER CONVERSION DEVICE

A first DC-DC conversion circuit (101) and a second DC-DC conversion circuit (101a) that are connected in parallel to one casing (102) are operated independently, whereby even in the event of failureof semiconductor switching elements (107, 108, 107a, 108a) configuring either the first DC-DC convers...

Zusammenfassung:	A first DC-DC conversion circuit (101) and a second DC-DC conversion circuit (101a) that are connected in parallel to one casing (102) are operated independently, whereby even in the event of failureof semiconductor switching elements (107, 108, 107a, 108a) configuring either the first DC-DC conversion circuit (101) or the second DC-DC conversion circuit (101a), power supply of a power conversiondevice (100) is continued by operating only the DC-DC conversion circuit that operates properly. 通过使并联连接至一个筐体(102)的第一直流-直流转换电路(101)和第二直流-直流转换电路(101a)分别独立地工作，由此即使在万一构成第一直流-直流转换电路(101)和第二直流-直流转换电路(101a)中的任一个的半导体开关元件(107、108、107a、108a)发生故障的情况下，也通过仅使正常工作的直流-直流转换电路工作，从而使功率转换装置(100)继续供电。
