功率转换装置、电车及联锁顺序试验的控制方法
摘要：
功率转换部(115)进行将AC或DC电力分别转换成用于驱动马达(105)的电力并提供给负载的AC模式或DC模式的转换动作。电源输出切换开关(111)根据联锁顺序试验信号的输出，切断从电源(101)到功率转换部(115)的电力供应，该联锁顺序试验信号用于指示联锁顺序试验的执行。在输出联锁顺序试验信号、并利用电源输出切换开关(111)切断对功率转换部(115)的电力供应的情况下，控制部(116)根据联锁顺序试验信号的输出和非输出的切换历史，执行AC模式或DC模式的控制，该AC模式或DC模式的控制用于在功率转换部(115)中执行与提供给功率转换部(115)的电力相对应的转换动作。
摘要（英）：

A power conversion unit (115) performs an AC mode or DC mode conversion operation in which AC or DC power is converted to power for driving a motor (105) in order to supply a load. In response to the output of a sequence test signal instructing execution of a sequence test, a power output switching switch (111) shuts off the supply of power from a power source (101) to the power conversion unit (115). When the sequence test signal has been output and the supply of power to the power conversion unit (115) has been shut off by means of the power source output switching switch (111), a control unit (116) controls the AC mode or DC mode in order to cause the power conversion unit (115) to execute a conversion operation corresponding to the power supplied to the power conversion unit (115) in accordance with the switching history of the sequence test signal output and non-output.
