Abstract
AbstractThis paper presents a novel two‐switch high step‐down converter based on the conventional Ćuk converter. The proposed converter features lower gain and higher efficiency due to reduced switching and conduction losses. Notably, it enables zero current switching turn‐on for switches without requiring additional components, enhancing its efficiency. The low voltage stress on the switches significantly impacts efficiency. Additionally, its simple topology reduces the component count, further improving efficiency. Zero current switching turn‐off condition for the diode effectively addresses reverse recovery problem. To validate its performance, a prototype operating at 200 W output power, 300 V input voltage, 24 V output voltage, and 40 kHz switching frequency is implanted.
