Abstract
A new four level half-bridge converter is proposed in this paper. Compared to a conventional half-bridge converter and an asymmetric half-bridge converter, the proposed converter has less stress on power switching components and have smaller output inductor. Zero-voltage-switching condition is also achieved with the proposed converter. The operational principle, DC conversion ratio and ZVS analysis are presented. Experimental results are demonstrated to verify the feasibility and advantages of the new topologies.
