In this study, an interleaved soft switching boost converter suitable for high step‐up applications is proposed. Zero voltage switching and zero current switching characteristics could be provided for main switches and main diodes, simultaneously. Also, the auxiliary semiconductors can achieve soft switching. Since all the utilised diodes operate under soft‐switching conditions, the diodes reverse recovery problem is perfectly alleviated. Due to the unique operation of the proposed topology, the converter is controlled by variant switching frequency and high voltage ratios can be achieved. Further, the precise theoretical analyses and design procedure of the converter have been investigated utterly. Finally, according to the designed characteristics, a laboratory prototype with 60 V input voltage and 300 V output voltage is built and tested, which is in agreement with theoretical analyses.
