Abstract :This paper suggests a maiden topology of step-up dc/dc transformer-less converter on basis of the partial power processing concept which has been integrated with the classic boost converter structure. This converter has a high gain as compared to the conventional boost converter. The input dc power is directly connected to the output capacitors and load without being processed by the converter. Where-through, the voltage stress of semiconductors comes to be lower than output voltage. To verify and clarify the suggested converter, the experimental prototype has been presented along with relevant mathematical principles. To sum up, the MATLAB simulation results and the experimental results have transparently approved high efficiency of proposed converter as well as its feasibility.
