A New Hybrid Zeta-Boost Converter With Active Quad Switched Inductor for High Voltage Gain

For renewable sources application like smart grids, microgrids, etc. high voltage gain converter becomes a fundamental unit. In this article, a new hybrid circuit of zeta and boost converter based on active-quad-switched-inductor (AQSL) is proposed. The discontinuous input current in classical zeta circuit determines the less consumption of input source. However, the proposed hybrid zeta-boost converter provides a higher voltage gain with continuous input and output currents. It achieves higher voltage gain devoid of the high-frequency transformer, and multiple stages of diode and capacitor circuit. The mode of operation, boundary region, and non-ideal model of the proposed converter are presented. Design consideration and a comparison study with recent circuits are provided. The design circuitry of the proposed converter investigated and the functionality of the suggested circuit is validated.
