Configurations of Modified SEPIC Converter with Switched Inductor Module (MSCsI) for Photovoltaic Application: Part-II

The proposed work is extended configurations of Modified SEPIC Converter (MSC) and Modified SEPIC Converter with Switched Module (MSCSI). The proposed three configurations are derived by replacing two inductor of MSC by two Switched Inductor (SI) modules, namely Modified SEPIC Converter with XYL configuration (MSCSI-XYL), Modified SEPIC Converter with LYZ configuration (MSCSI-LYZ) and Modified SEPIC Converter with XLZ configuration (MSCSI-XLZ) to improve or increase the overall gain of the converter. The key feature of proposed configuration is: (i) single switch topologies, (ii) no reverse current flow from load to source due to large inductor at the input side, (iii) high voltage conversion ratio. The detailed analysis of three configurations is done in terms of component count, voltage conversion ratio and efficiency. The mathematical analysis and simulation results validates the functionality of three configurations.
