摘要：
本发明具备如下结构：若在第1三相电压指令中第1中间相电压指令与第1最小相电压指令相接近，则从相当于第1两相调制的第1运算处理切换成第2运算处理，从而根据第1三相电压指令运算第1三相施加电压，若在第2三相电压指令中第2中间相电压指令与第2最小相电压指令相接近，则从相当于第1两相调制的第3运算处理切换成第4运算处理，从而根据第2三相电压指令运算第2三相施加电压。
摘要（英）：

The present invention is provided with a configuration in which, if a first intermediate phase voltage command and a first minimum phase voltage command in a first three-phase voltage command are close to each other, switching from first calculation processing corresponding to first two-phase modulation to second calculation processing is performed to calculate a first three-phase application voltage from the first three-phase voltage command, and, if a second intermediate phase voltage command and a second minimum phase voltage command in a second three-phase voltage command are close to each other, switching from third calculation processing corresponding to the first two-phase modulation to fourth calculation processing is performed to calculate a second three-phase application voltage from the second three-phase voltage command.
