| description | To realize control to match a bus voltage to a predetermined setting voltage even when the bus voltage is smaller than a system power supply voltage.SOLUTION: A d-axial control part 11 of a PWM converter controller 1, generates a terminal voltage deviation of a minus by subtracting a terminal voltage command feedback vfrom a power supply voltage command ewhen a bus voltage is smaller than a system power supply voltage, generates a current command iof a value of the minus so that the terminal voltage deviation is equal to 0, and generates a d-axial voltage command v. A q-axial control part 12 generates a q-axial current command iso that a bus voltage deviation between a bus voltage command eand a bus voltage feedback eis equal to 0, and generates a voltage command so that a current deviation between the q-axial current command iand a q-axial current feedback iis equal to 0. The q-axial control part 12 adds a q-axial compensation voltage or the like to which the current command iof a minus value to the voltage command, and generates a q-axial voltage command v.SELECTED DRAWING: Figure 3
【課題】バス電圧が系統電源電圧よりも低くなった場合も、バス電圧を所定の設定電圧に一致させる制御を実現する。【解決手段】ＰＷＭコンバータ制御装置１のｄ軸制御部１１は、バス電圧が系統電源電圧よりも低くなると、電源電圧指令ｅ1*から端子電圧指令フィードバックｖ1*を減算してマイナスの端子電圧偏差を生成し、端子電圧偏差が０となるようにマイナスの値の電流指令ｉd*を生成し、ｄ軸電圧指令ｖd*を生成する。ｑ軸制御部１２は、バス電圧指令ｅbus*とバス電圧フィードバックｅbusとの間のバス電圧偏差が０となるようにｑ軸電流指令ｉq*を生成し、ｑ軸電流指令ｉq*とｑ軸電流フィードバックｉqとの間の電流偏差が０となるように電圧指令を生成する。ｑ軸制御部１２は、電圧指令に、マイナスの値の電流指令ｉd*が反映されたｑ軸補償電圧等を加算してｑ軸電圧指令ｖq*を生成する。【選択図】図３ |
