三相電流形PWMコンバータ制御モデルとその有限整定制御

抄録

In this paper a dynamic circuit system model of active three-phase current-source PWM converter for Power Factor Correction is described on the basis of instantaneous space vectors. The formulation of the discretized value system and control algorithm to achieve the deadbeat responses of state variables in the utility AC side low pass filter of this converter are evaluated and discussed from an experimental point of view. The system response is much faster and transient oscillations of both source current and capacitor voltage are suppressed effectively, though the state variable in the state feedback is only the current.
