Abstract: In this modern era due to various application running on high voltage, the requirement to fulfil this demand at lower operational cost is very essential. In this paper, high dc voltage is obtained by implementing step up converter (boost converter) with multistage Cockcroft Walton voltage multiplier. This step-up converter operates in the continuous conduction mode, due to this the voltage stress across the switches are reduced and there by improves the performance of the converter with reduced ripples. The boost converter consists of four IGBT switches and operated at two different independent frequencies. The high DC voltage is obtained at lower duty cycle. The proposed topology is validated by Matlab simulation
