Abstract
In this paper, the analysis and design of Sliding Mode Controller (SMC) based Cuk rectifier for Power Factor Correction in a three phase system is presented. A new and systematic technique for the selection of sliding surface co-efficients to implement SMC is attempted The front end is a three phase AC to DC converter followed by DC-DC Cuk converter modules with the common DC output. The control strategy is based on outer voltage loop control and three inner SMC current controllers. This type of three-phase three switch PFC converter features a simple and robust configuration compared to conventional six switch topology. Simulation results are presented to validate the approach. Simulation results reveal that SMC control can achieve good output voltage regulation and also provide improved robustness in shaping the input current in the presence of load variations.
