Dual-Switch Quadratic Zeta Converter

A novel dual switch quadratic Zeta architecture with a broad conversion ratio and non-inverting output voltage features is presented in this paper. It has broader bucking characteristics in comparison to the Zeta converter and provides a continuous source current. The theoretical circuit analysis and subsequent simulation will verify the features. The transfer function is realized via state-space modeling, and pole-zero plots are compared with the traditional Zeta converter topology to elaborate on its stability. PI controller is designed to reduce the settling time of the converter.
