Abstract

The zero-voltage-switching combined DC/DC three-level converter, just has six switches, and the voltage stress of all switches is ensured to be only the half of the input voltage, especially suitable for high-voltage input situations, and the converter can reduce the output filter significantly at the mode of three-level and two-level. The small-signal transfer function is obtained by modeling analysis based on small signal of the converter. According to the proposed block diagram of closed-loop system, the closed-loop transfer function of the converter is deduced. The established closed-loop system model is simulated through Matlab, the experiment and simulation results are in positive to the analysis showing the feasibility of the established model.
