PROJECT TITLE :

Virtual-Flux-Based Predictive Direct Power Control of Three-Phase PWM Rectifiers With Fast Dynamic Response

ABSTRACT:

This paper proposes a power predictive control (PPC) technique for three-section pulse width modulated rectifiers without a proportional-integral controller. The proposed PPC method calculates the optimized voltage vector by analyzing the relationship between the virtual flux, active power, converter voltage, and filter parameters. So, an overshoot will not occur and the fast and accurate power control becomes attainable. The predictive algorithm computes the ability error that might be created by applying every vector and selects the one that contributes the minimum error. The simulation and experimental results prove that the proposed methodology provides an wonderful steady-state performance and quick dynamic response.
