Abstract	This project proposes an improved transformer less high step-up dc-dc converter using Cockcroft Walton voltage multiplier. The low input DC voltage is boost up by a boost inductor in DC-DC converter and the proposed circuit performs the inverter operation. The n-stage CW-voltage multiplier is applying low input AC voltage to high output DC voltage. It provides continuous input current with low ripple, high voltage gain, reduced switching losses, low voltage stress on the switches, diodes and capacitors and also improving efficiency of the converter. The power switches having two independent frequencies. One of which operates at high frequency to minimize the size of the inductor while the other one operates at relatively low frequency according to the desired output voltage ripple. Voltage ripples produced during the motor operation is reduced in this proposed method. The main advantage of this project is that it increases the given input voltage by multiplying it without any use of transformer but just with the few switches, diodes and capacitor. The proposed converter can be applied to various applications like solar energy, fuel cells, hybrid vehicle.
