Abstract:  In this manuscript a DC non-isolated converter model with high static voltage gain module is presented. The proposed converter has the feature of stable frequency and stable output voltage. It also achieves high voltage conversion, high efficiency, low voltage stress and less switching loss. The voltage tripler technique is implemented in the proposed model. The designed converter model attains high static gain with reduced duty cycle. The proposed single switch converter is controlled by fuzzy-PI controlled technique. The working process of the converter under Continuous Conduction Mode (CCM) is explained. The 30 V input source is boosted up to 400 V. The simulation of the presented converter is done with MATLAB simulink. The hardware prototype is also tested and results are analysed.

Keywords: Continuous conduction mode, duty-cycle, high voltage gain, fuzzy-PI, voltage tripler
