The projected 2L-Y DC-DC Converter topologies are new members of the XY converter family. The 2L-Y converter is a combination of two single stage converters consisting, one is 2L converter and another is Y converter. Based on the configuration of Y converter four new topologies called a 2L-LVD converter, 2L-2LVD converter, 2L-2LCVD converter and 2L-2LCmVD converter are derived, discussed and analyzed in this paper. Due to higher conversion ratio capability of the proposed 2L-Y converter, it provides a workable solution for photovoltaic and electrical drive applications. The striking features of 2L-Y converter topologies are only one controlled device, negative output, Transformer-less topology, compact structure and having a minimum internal resistance. The proposed 2L-Y converters are simulated into MATLAB and simulation results are confirmed the theoretical analysis.
