Abstract: This Paper proposes a Novel and Modified Voltage Oriented Control (M-VOC) strategy of an Active Front-End (AFE) Rectifier that can give unity power factor at input side and regulated DC voltage at output side with reversible/bidirectional power flow. The proposed rectifier with M-VOC can find its place in applications like Wind energy conversion systems, DC load for electronic equipment, and adjustable AC drives. Simulation Analysis is done on this M-VOC strategy for an Active Front-End (AFE) Rectifier on MATLAB/ Simulink platform with the verification on the validity of the proposed system. The proposed Rectifier with M-VOC strategy gives good transient/dynamic response for the variations of load at output side. It also gives a pure sinusoidal input current with the elimination of harmonics so that this proposed Rectifier can be used in the case of back to back 2/3 level voltage source converters of wind energy systems that supports bidirectional power flow.
