| description | To implement stable control and to improve workability in selecting a semiconductor switching element by uniformizing partial current charge between multiple PWM converters.SOLUTION: When controlling two PWM converters, a PWM converter control device 1 branches a d-axis current command ithat is generated by a terminal voltage constant controller 10 and a q-axis current command ithat is generated by a bus voltage controller 15 into a first system and a second system. In the first system, a d-axis voltage command vand a q-axis voltage command vare generated and outputted to PWM controllers 21-1a to 21-1c, a gate of a semiconductor switching element of each phase in the PWM converter is turned on/turned off by the PWM converter control device 1. In the second system, a d-axis voltage command vand a q-axis voltage command vare generated and outputted to PWM controllers 21-2a to 21-2c and a gate of a semiconductor switching element of each phase in the PWM converter is turned on/turned off by the PWM converter control device 1.SELECTED DRAWING: Figure 1
【課題】複数のＰＷＭコンバータの間で電流分担を均一にすることで、安定した制御を実現すると共に、半導体スイッチング素子を選定する際の作業性を向上する。【解決手段】ＰＷＭコンバータ制御装置１は、２台のＰＷＭコンバータを制御する際に、端子電圧一定制御器１０にて生成したｄ軸電流指令ｉd*及びバス電圧制御器１５にて生成したｑ軸電流指令ｉq*を、第１系統及び第２系統に分岐させる。ＰＷＭコンバータ制御装置１は、第１系統において、ｄ軸電圧指令ｖd1*及びｑ軸電圧指令ｖq1*を生成し、ＰＷＭ制御器２１−１ａ〜２１−１ｃに出力し、ＰＷＭコンバータの各相の半導体スイッチング素子のゲートをオンオフし、ＰＷＭコンバータ制御装置１は、第２系統において、ｄ軸電圧指令ｖd2*及びｑ軸電圧指令ｖq2*を生成し、ＰＷＭ制御器２１−２ａ〜２１−２ｃに出力し、ＰＷＭコンバータの各相の半導体スイッチング素子のゲートをオンオフする。【選択図】図１ |
