New Interleaved Structure with High Voltage-Gain and Low Voltage-Stress on Semiconductors

Abstract

In this paper a high voltage-gain interleaved structure for DC-DC converters is proposed. This structure provides high voltage-gain with reasonable number of elements and low voltage-stress range. Also continuous input current and low current ripple are other advantages of this structure. These features make this converter suitable to use in renewable energy sources. In this paper, proposed converter is analyzed completely and all relations in different modes will be achieved. In order to realize improvement in this converter, proposed converter will be compared with related structures.
