Study on High Step-up DC-DC Converter with High Gain Cell for PV Applications

High gain dc-dc converters are fast growing switching power converters for Photo Voltaic (PV) applications. Researchers are developing different topologies to achieve higher voltage gain, low switch stress, low ripple, and cost efficient converters. This paper studies various High Gain (HG) cells and its performance is analyzed by combining the cell to the quadratic boost converter. We made a comparative study on all the types of HG cell concerning voltage gain, voltage stress and switch utilization factor, and efficiency. Simulation is carried out in the nl5 simulator. Finally, an efficient HG cell is determined in positive output HG cell.
