Direct Power Control Strategy for PWM Rectifier with the function of an Active Power Filter Based on a Novel Virtual Flux Observer

Abstract

For improving the quality of the energy
transfer from the power supply to the load, and
reducing the harmful effects of the harmonics
generated by nonlinear load. We propose a new
multi-function converter (MFC) as an efficient
solution to improve the power quality. This paper
presents a new DPC strategy based on virtual
flux Observer and Space vector Modulation to
control PWM rectifier achieving by this unit
power factor and reducing the harmonic current
of the non linear load. The good dynamic and
static performance under the proposed control
strategy is verified by simulation and experiment.
