Abstract

This paper presents a method of mitigating the transient overshoots of dc-dc converters undergoing large load disturbances. The method involves a small power auxiliary circuit which exists as an energy buffer to provide a smooth absorption and release of excess energy from and to the main dc-dc converter during transients. In the method, the regulation of the current magnitude of the converter and energy storage of the auxiliary circuit are guaranteed by the relevant control schemes. The cost and size of the auxiliary circuit will be relatively small as it only operates intermittently. In this paper, the voltage deviation analysis and the auxiliary circuit design guideline are provided. Experimental results validating the approach are presented. © 2012 IEEE.
