This paper presents the output voltage regulation characteristics and the dynamic performance of an RSCC using a phase-shift control. The proposed phase-shift control realizes soft switching operation even if the output voltage was changed, and it achieves a higher conversion efficiency. A theoretical analysis shows that the RSCC can reduce its inductor volume compared with a buck converter when its output voltage range is limited within 19–81% of its input voltage. Experimental results verify the operation characteristics of the proposed method and show the improved conversion efficiency more than 99%.
