A New and Effective High Gain DC-DC Converter Topology with Hybrid Configuration for Solar Photovoltaic-Based Power Generation Systems

For distributed PV systems to effectively utilize solar photovoltaic (PV) energy sources, the inclusion of a stepup converter with a substantial output gain is crucial due to the comparatively lower voltage output. Numerous dc-dc converters are existing in the literature; each has merits and demerits. Therefore, in this study, another new dc-dc boost converter is introduced for the above-said application by integrating the boosting technologies called voltage multiplier cell, Dickson switched capacitor, and coupled inductor with the traditional boost converter, resulting in a hybrid converter configuration. The suggested converter is provided with a single MOSFET switch and operated at an optimum duty ratio. The suggested hybrid converter attains an optimal conversion efficiency and high output voltage gain, along with lowered MOSFET current and voltage stresses. The theoretical investigation of the suggested hybrid converter is validated through the simulation using the PLECS simulation tool. The results proved that the suggested converter could produce high step-up gain with high efficacy, continuous source current and less voltage stress than the few other converters in the literature.
