    • A LPF extracts DC component of a current detection value of an inverter input current. A subtracting section 4 calculates a difference between a current command value and the DC component of the current detection value. A current controller 5 produces two-phase PWM signals Sa and Sb complementary to each other, from the current difference. Further, an integrating circuit 7 integrates output terminal voltages Vu, Vv and Vw of the inverter to convert the output terminal voltages Vu, Vv and Vw into a magnetic-flux information Φu, Φv and Φw. A logic conversion section 8 converts the magnetic-flux information Φu, Φv and Φw into 120-degree conduction patterns S1′-S6′ to output the 120-degree conduction patterns S1′-S6′. Then, a logic circuit section 9 executes a logic synthesis between the PWM signals Sa and Sb and the 120-degree conduction patterns S1′-S6′ to output gate signals S1-S6.
    • LPF提取逆变器输入电流的电流检测值的DC分量。 减法部分4计算当前指令值与当前检测值的直流分量之差。 电流控制器5根据电流差产生彼此互补的两相PWM信号Sa和Sb。 此外,积分电路7对逆变器的输出端子电压Vu,Vv,Vw进行积分,将输出端子电压Vu,Vv,Vw变换为磁通量信息Phiu,Phiv,Phiw。 逻辑转换部分8将磁通量信息Phiu,Phiv和Phiw转换成120度的导通图案S1'-S6'以输出120度的导通图案S1'-S6'。 然后,逻辑电路部分9执行PWM信号Sa和Sb之间的逻辑合成以及120度导通图形S1'-S6'以输出门信号S1-S6。
