This paper proposes a new nonisolated dual‐input, single‐output (DISO) DC–DC converter. In the proposed converter, by utilizing two three‐winding coupled inductors at the primary of each input ports, the capabilities of high‐voltage conversion ratio and elimination of input current ripple are achieved for all range of duty cycles (0 < D < 1). Therefore, the proposed converter is applicable in renewable energy systems. The voltage conversion ratio can be increased without selecting high duty cycles for the switches or by using a high number of components. Also, the voltage stresses on switches of the proposed converter are in low level. The proposed converter has simple switching pattern and the two switches turn on/off inversely. Unlike the interleaved converters, the proposed converter has a single conversion ratio for all adopted duty cycles of the switches (0 < D < 1). In this study, the proposed converter is analyzed and the required conditions for eliminating input current ripple, the voltage and current stress on the semiconductors, and the voltage gain are calculated. To confirm the theoretical results, experimental results are extracted for a 14‐V/19‐V input and 400‐V output voltages for the operating power of 350 W.
