摘要：
In this paper a new non-isolated high step-up interleaved cascade converter is presented. In comparison with the conventional cascade boost converter, the proposed converter has a higher voltage gain, lower input current ripple and reduced voltage stress for the switches and diodes. Besides, unlike the conventional cascade boost converter, in the proposed converter the input current is shared between inductors and hence the converter can be implemented with lower current rated inductors. Thus, the converter size and conduction losses are reduced and the efficiency is increased. The proposed converter is analyzed and experimental results of a 200W laboratory prototype are presented.
