This paper describes a Fuzzy Logic approach to Shunt Active power filter (SAPF) versus Hybrid Active Power Filter (HAPF) using Simulink. Here hysteresis controlled PWM method is applied to the SAPF and HAPF as a current controller and Fuzzy logic controller as a inverter dc voltage controller. To reduce harmonics, Shunt Active Power Filters (SAPFs) are used with various control schemes, but Hybrid Active power filter is a power electronic device which has both the characteristics of passive power filters and active power filters, which helps in cancelation of the harmonics by producing compensating signal. The fuzzy-hysteresis controller is designed and its simulation results are presented for both the filter types, showing acceptable THD results for the word length used in the fixed-point computations involved in the switching sequence generation. The results of the above controller are compared with the Indirect current controller.
