Abstract Burning fossil fuels not only contributing towards emission of greenhouses gases that causes very harmful effects on atmosphere but also making world fossil fuels reserves running short to meet the future energy demand of our offspring. In order to cope with the aforementioned drawbacks of fossil fuels consumption we need to go with an alternate energy source which having ability to address the both loophole lying with fossil fuels use to meet electricity energy needs. In this regard currently world is rushing towards renewable energy resources because of their abundant availability and widespread distribution across globe besides their characteristic of being clean i.e no contribution of greenhouse gas emission. Among them wind and solar has attracted great attention. But among these renewable energy resources wind and solar have drawn great attention owing to their abundant and widespread distribution characteristics. Though the power generation from wind and solar is considered unreliable. However, enormous capability of power generation yet makes them attractive energy resource. But the generated power from these resources i.e solar and wind in particular, solar having very low magnitude to meet the load demand. Keeping their low power generation ability in view attempts were made to resolve this grim concern. In this regard, different researchers strived hard to develop a device known as boost converter. However, conventional topologies have drawbacks of power switch voltage stress, diode recovery issue, and low efficiency along with complex circuitry. In this paper efforts are made to device a convert that has capacity to address the traditional topologies’ drawbacks. Further the proposed converter is equipped with coupled inductor and switched capacitor technique. Moreover, Zero current switching is employed for power switch turn ON and diode turn OFF.  The converter is intended to operate at moderate duty cycle having input voltage 15, output voltage 180v with 250w rating.
