With the increase in the usage level of solar energy all across the world, it is necessary to deliver a better output with reduced losses. Conventional PV systems seem to be an efficient solution to the environment but energy conversion efficiency is still low. The purpose of this system is to enhance the output power quality with mitigated total harmonic distortion developed due to non-linear loads. The proposed system consists of PV system connected to the non-linear load through Zeta converter using fuzzy logic controller. The DC power from the PV panel is boosted using Zeta converter which provides suitable output with reduced losses. A DC capacitor connected across VSI acts as a series hybrid active power filter (SHAF) to reduce harmonics and compensates reactive power. This system is simulated using MATLAB/SIMULINK. The performance is analysed and compared with conventional PV system which uses DC-DC boost converter. Zeta converter with FLC provides better harmonic compensation, low ripple voltage and higher output than boost converter with FLC. The result is compared in terms of its input, output and THD. It is concluded that the proposed technique provides improved power quality.
