Abstract :
This paper presents operating performance of a switched-capacitor-based resonant converter (SCRC) using a phase-shift control method. The proposed phase-shift control realizes zero-voltage switching operation, and thus achieves a high-conversion efficiency. A theoretical analysis shows that the SCRC can reduce its inductor volume compared with a conventional buck converter when the output voltage range is within 19%-81% of its input voltage. Experimental results verify the operating characteristics of the proposed method and show the improved conversion efficiency of more than 99%.
