This paper presents optimized fuzzy variable structure control design in a three phase rectifier to correct the power factor. This control strategy combines fuzzy and sliding mode control algorithms. Few fuzzy rules are used for this scheme. The parameters of the fuzzy controller are adjusted by using the VSC for a better response and robustness. To improve the behavior of the system is applied a gradient optimized method to find better matrix rule values. The simulations of the three-phase rectifier with controlled current are carried out on a DSP. The control scheme presented here offer higher robustness and it is easier to adjust and implement.
