High step-up converter based on charge pump and boost converter

In this paper, a novel step-up converter is presented, where the charge pump concept, combined with the traditional boost converter structure, is utilized. Although two inductors are used in such a converter, the difference in value between the two inductors does not degrade the performance of this converter. Besides, the behavior of this converter is similar to the traditional boost converter, and hence control of this converter can be realized easily. In this paper, the basic operating principles of the proposed converter are presented along with some experimental results to demonstrate the effectiveness of this converter.
