Abstract

New members of XY converter family topologies are proposed in this treatise for a high-voltage/low-current renewable application. Based on the X Converter, the whole existing X-Y Converter family is categorized into four categories; L-Y, 2L-Y, 2LC-Y and 2LCm-Y converter. Four new 2LC-Y topologies (2LC-LVD, 2LC-2LVD, 2LC-2LCVD and 2LC-2LCmVD) converters are presented in this treatise which offer an effective solution for renewable applications requiring a very high voltage conversion ratio such as a Photovoltaic Multilevel Inverter (PV-MLI) system, hybrid electrical drives and automotive applications. The noticeable features of the proposed 2LC-Y converter topologies are: I) Only one power control switch and input source; ii) High negative output voltage with moderate duty ratio; iii) Low output current and minimal internal resistance; iv) Transformer-less converter topologies; v) High voltage conversion ratio; vi) Minimal number of power devices and components. Working and output voltage analysis of the proposed 2LC-Y converter topologies are discussed in details. The MATLAB simulation results are provided and good agreement with theoretical analysis is shown. Simulation results also validate the performance and functionality of the proposed 2LC-Y converter topologies of the XY converter family.
