Abstract: Luo converter is a developed converter which transfers the voltage based on lifting and achieves a high voltage gain in geometric progressive law. Researchers show more interest on control of Luo family converters while their procedural steps involved in design is not detailed to gratify the beginner in the field. In regulated power supply applications, Luo converters are more preferred if they operated in soft switching mode. Soft switching techniques like Zero Voltage Switching (ZVS) has reduced switching losses and hence improved efficiency and life of power semiconductor switches. This study takes up and provides complete design of Positive Output Elementary Super Lift Luo Converter (POESLLC) for the 25.92 W rating, firstly. Secondly, the performance evaluation of ZVS based POESLLC over hard switched POESLLC is aimed. Proportional Integral (PI) control of POESLLC for hard switched and ZVS switching are compared in MATLAB-simulink platform.
