Ultra High Step‐Up Soft Switching Converter Based on the Interleaved Structure

Energy Science &Engineering, Volume 14, Issue 1, Page 540-556, January 2026.
The proposed topology provides high voltage gain and enhanced efficiency at low duty cycles, thereby reducing conduction losses in the switches. Its interleaved structure ensures current sharing, while the switches experience both low voltage and low current stress, further decreasing conduction losses.
