摘要：

In this paper, a four-level dc/dc buck converter is introduced. The primary application for this converter is to regulate the center capacitor voltage in a four-level inverter system. The steady-sate and average-value models for the proposed converter are developed and compared in simulation. The converter was constructed in the laboratory and verified on a four-level motor drive system. It was shown that the four-level dc/dc converter provides capacitor voltage balancing and allows higher output voltage utilization from the inverter.
