High Step-Up DC-DC Converter Soft Computing Module for PV Module

The PV module demonstrates a significant market expansion as a photovoltaic (PV) power generation technology.The requirement of a high voltage gain converter exists for connecting PV modules to the power grid through a dc-ac inverter.A converter with floating active switches should be studied because it will protect PV panel users and installers by blocking power during ac module shut offs.The converter obtains high voltage gain through effective operation without requiring excess duty ratios or many turns-ratios like linked inductors; it reuses the coupled inductor leakage energy for improved efficiency.These features contribute to the module achieving remarkable efficiency performance.The paper presents analytical results for steady state operation of continuous and discontinuous and boundary conduction modes as well as a detailed description of working principles.The developed prototype circuit of the suggested converter functions with 15V input voltage, 200V output voltage, and 100W output power.The element achieves 95% efficiency under full load while reaching its highest efficiency of 95.3%.
