In this paper, Performance of Cuk ac–dcconverter is presented with hysteresis current and voltage loop. DC- DC converter is used to calculate the power . To reduce the harmonics filters are designed. In this paper shunt active filter is used to reduce the harmonics. Switching sequences is controlled by using Hysteresis Current controller. It improves the output of the converter. Converter is operates in two modes one is voltage controller mode and another is current controller mode. Power factor correction is used in input side to regulates input dc bus, controller is used in output side to regulate the output bus voltage. In this paper, converter operation is discussed to explained and described the controlling strategy and total harmonic distortion of input current. Finally all operation is compared with steady-state behavior, THD, and efficiency.
