Three-Phase Shunt Active Filter for Cuk-Sepic Fused Converter with Solar–Wind Hybrid Sources

At the present time, the use of nonconventional energy resources is having a huge demand as the conventional energy sources are depleting in nature and causing more pollution which ensures the need of renewable energy resources. This paper deals with the design of a cuk-sepic converter with a three-phase inverter feeding a nonlinear load. Harmonics will be introduced to the system due to the use of nonlinear load which will affect the equipment in both source and load end, so there is a need of filter to mitigate the harmonics. Here, a shunt active filter is used which will reduce the harmonics introduced in the circuit. The desired low harmonic three-phase voltage is obtained as per the IEEE standard of below 5% as the filter results in 1.33% total harmonic distortion (THD). The simulations are carried out and analyzed by using PSIM software.
