Very high voltage step-up Integrated Quadratic-Boost-Zeta converter

This paper proposes an analysis of a high step-up DC/DC converter named Integrated Quadratic-Boost-Zeta converter. It is based on the combination of two well-known DC/DC converter circuits, the Isolated Zeta converter and the Quadratic-Boost converter. The aim of this paper is to analyze the voltage static gain, the voltage and current stresses on the components of the converter as well as its main features. Additionally, the derivation for three different alternative topologies is presented and their principles of operation, features and limitations are discussed. Experimental results obtained from a laboratory prototype rated at 250W and 100 kHz prove the feasibility and reliability of the proposed converters.
