Abstract

The work elucidated in this scientific article presents a novel non-isolated high gain switched capacitor (HGSC) DC-DC converter engulfed for carbon neutral energy applications. A hybrid utilization of complementary switching approach switches enables simplified control and high voltage gain of HGSC even at low duty cycle owing to the switched capacitor along with boost inductors. Further, the proposed structure also features high efficacy, reduced voltage stress and current stress on semiconductor switching devices. The proposed HGSC DC-DC converter principle of operation along with the steady-state analysis and different switching stages were discussed in detail. Small signal analysis has been performed to analyze the stability of the proposed converter, whereas an averaging technique is performed to know its dynamics performance. Furthermore, the converter is thoroughly analyzed in terms of power losses. For comparing the practical efficiency of the designed converter, non-idealities voltage gain is derived. The efficiency of the proposed converter is validated practically and extensive performance comparison is carried out with other solutions in the literature. When a supply of input voltage 20 V feed into the proposed converter. It produces an output voltage of 140 V to 240 V output. A 200W laboratory proto model is developed; accordingly conducted extensive experimental analysis to validate the feasibility of the proposed HGSC DC-DC converter topology.
