In this study, the analysis and design of a three‐phase AC–DC converter followed by DC–DC Cuk converter modules to achieve unity power factor is presented. Two methods of reference current generation techniques are employed. In the first scheme, reference current is generated using instantaneous symmetrical component theory under balanced supply conditions. In the second scheme, extended synchronous detection methods such as equal current criterion, equal power criterion and equal impedance criterion are used for reference current generation under unbalanced supply conditions. The control strategy uses three hysteresis current controllers for source current shaping and an outer voltage loop with proportional‐integral controller for load voltage regulation. To validate the proposed method, a prototype controlled by dSPACE signal processor is set up. Simulation and experimental results indicate that the proposed system offers regulated output voltage for wide load variations and provides power factor close to unity.
