Abstract
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 vector modulation scheme. The formulation of the discretized system and control algorithm to achieve the deadbeat responses of state variables in the utility AC power side low pass filter of this converter are evaluated and discussed from an experimental point of view. The system response of this converter 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 obtained from the precise current sensor interface circuit.
