In this paper, Cockcroft Walton Voltage Multiplier (CWVM) DC-DC converter generates high DC voltage gain is attained without using the step-up transformer is proposed. It displays an efficient output power to load as increasing the multiplier stages. Input voltage from Photo-Voltaic (PV) source is low and CWVM DC-DC converter produces more output voltage. Output voltage from the proposed converter is providing constant current to the switches and diode in the circuit, less voltage ripple, and high voltage gain. The proposed method consists of 3-stages. Output of each three stage is 270V. The PV based CWVM DC-DC Converter and its designed are verified using Matlab/Simulink software.
