PROBLEM TO BE SOLVED: To carry out energy processing, when stopping an inverter output without making the breakdown voltage of an element large and moreover, without having to provide special circuit. SOLUTION: In step SP1, the stop signal of an inverter output Sinv is inputted and in step SP2, it is determined whether the stop signal of the inerter output Sinv is indicating the stop of the inverter output. When it is so, a transistor control signal is outputted that instructs all transistors to be turned off in step SP3. In step SP4, a waiting processing is carried out for a given period of time. In step SP5, another transistor control signal is outputted, that instructs the bottom arm transistors of all phases to be turned on. |
