专利汇可以提供Voltage type inverter专利检索,专利查询,专利分析的服务。并且PURPOSE:To suppress the charging current flowing into a smoothing capacitor of the subject inverter by a method wherein a DC reactor, which was connected in between a forward converter and an inverse converter, is attached to the intermediate terminal, and one end of the smoothing capacitor is connected to the intermediate terminal. CONSTITUTION:The current flowing to the inverse converter 4 is increased when the inverse converter 4 fails to commutate or a load 6 is short-circuited, and as a result, voltage is generated on the DC reactor 7. At this time, as the voltage between the terminals 8 and 9 of the DC reactor 7 is directing toward opposite direction for the output of the forward converter 3, the charging current flowing to the smoothing capacitor from the forward converter 3 is suppressed. In the meantime, a DC current transformer 14 detects anything abnormal and a circuit breaker is turned to OFF position.,下面是Voltage type inverter专利的具体信息内容。
