A current based OCC technique implemented by DSP for a three-phase OCC rectifier

Abstract

In this work it is proposed a control strategy for a shunt Active Power Filter (APF) based on an One Cycle Control (OCC) Rectifier, implemented by DSP. An input resistance controller to set up dc-link voltage and a lead-lag compensator to average grid current is part of this work. In addition, as DSP implementation can increase the possibilities of control of complex systems. An example of this feature is further investigated, as the ability of proposed OCC based APF to control unbalanced non-linear load. Simulation and experimental results validate the proposed work.
