Abstract: This study deals with the design of Zeta converter with ZVZCS switching technique for better efficiency, lower total harmonic distortion factor and power factor correction. It requires simpler control circuitry with fewer external components added with SEPIC converter. The basic operation of Zeta converter is explained and PI filter is used to reduce the harmonics. Like SEPIC DC/DC converter topology, the Zeta converter topology also provides a positive output voltage from an input voltage for boost and buck purposes. Inverse of Cuk converter. ZVZCS switching technique is used to reduce the THD. The performance of Zeta converter in open loop and closed loop is obtained using MATLAB Simulink. Zeta converter in closed loop shows better performance than open loop. The performance of Zeta converter is compared by comparing both open loop and closed loop. Zeta converter in closed loop has low THD value and power factor near to unity.
