Modelling and simulation of front end converter for power quality improvement

This paper is concern with the modelling and simulation of three phase front end converter for power quality improvement. The space vector modulation technique is used to control the three phase front end converter. The objective of this work is to get unity power factor at the input side, dc link voltage regulation against load variation and reduction of harmonics in input side line current. The paper represents mathematical model of front end converter. The simulation results confirm the validity of the model and its control method.
