Description
次に、直列多重インバータ制御方式で、PS(Phase Shift)方式について説明する(特許文献1参照)。PS方式は、複数のキャリア信号の位相をシフトして電圧指令との比較を行う方式で、使用されるキャリア信号数は2n個である。また、これら2n個のキャリア信号をまとめて位相シフトキャリア群と呼ぶ。キャリア信号の位相シフトは、電圧歪みが最も低減される値「360°/キャリア信号数」で決定される。2段直列の多重インバータの場合、4つのキャリア信号を90°位相差で配置し、それぞれの単相インバータに対応させることで実現できる。この例について、図5にPS方式のキャリア信号と電圧指令値および出力電圧の関係を示す。

前記移動平均の幅Tcは、前記PWM制御の周期(キャリア信号の周期Tcarryの1/2n)と同じ時間とし、かつキャリア信号のピークと同期させ、
前記サンプリングの間隔Tsmpは、移動平均幅Tcの2分の1以下とし、キャリア信号と同期させることを特徴とする。
