Abstract

A New L-L Multilevel Boost Converter (L-LMBC) topology for high gain renewable energy application is proposed in this work. L-LMBC topology is designed to provide an operative solution for renewable energy applications which requires a high voltage conversion ratio and stack of the capacitor; such as a photovoltaic system with a fed Multilevel Inverter (MLI), electrical drives, automotive, hybrid electric cars, etc. The proposed topology is derived by attaching the Cockcroft Walton (CW) multiplier to an upper L converter of the LL topology of XY family. The mode of operation of L-LMBC with mathematical equations is also discussed in the detail. The noticeable features of proposed L-LMBC topology is i) Only one power control switch ii) High inverting output voltage from single input source iii) without the use of transformer iv) The number of CW multiplier levels can be added to achieve the voltage without changing the connection of main circuits. The Matrix Laboratory (MATLAB) simulation results are provided and the result validates the functionality, feasibility and design of the converter.
