Abstract
In this paper, a high step up Quasi –Z Source DC-DC converter is presented using hybrid switched capacitors switched inductor method to achieve high voltage gain. The proposed converter have solved the duty cycle limitation and voltage gain limitation while maintaining its main advantages such as low voltage stress on capacitors, diodes and switches. The proposed converter has a feature of flexible structure. The operating principle, related relationships and waveforms of the proposed converter are presented in this paper. Also, a comparison between the proposed converter and switched inductor QZS dc-dc converter is provided to confirm the superiority of the proposed converter. Simulations are done in MATLAB Simulink environment to attain high voltage gain.
