A Novel Low Loss, Medium Gain CI based DC-DC Boost Converter

An expeditious growth in population, urbanization and industrialization demands for non-polluted air for better life standards in smart cities, metro cities and urban areas. A move towards better life standards is to encourage green transportation for the needs of future generations. One such solution is to use electric vehicles (EVs), but still 3/4th of today's transportation had relying on petrol and their by-products-based engines due to lack of awareness, fire accidents, storage limitation, charging times and lack of charging infrastructure. So, to address one of the said limitations proposed a compact, efficient, and simple novel DC-DC converter for medium gain applications. It is first of its kind uses one controlled switch and two uncontrolled switches along with coupled inductor which also made the proposed converter to be the potential converter stage in the onboard charger, electrical drive system and fast charging infrastructure. A mathematical analysis carried out to find values inductance, capacitance, and duty cycle to get the required gain. The CI based converter is simulated in MATLAB Simulink environment under open loop and closed loop.
