Abstract

In a cascaded DC/DC system, stability degradation caused by converters' interactions, or intermediate voltage deviation caused by fast load transients can be reduced by using an active auxiliary circuit that emulates a passive RC damping circuit. However, the RC parameters used for addressing the two issues above should be different, because an RC circuit connected to the intermediate voltage bus may destabilize the source converter. This paper shows the analysis of such destabilization issue caused by the RC circuit, and presents a control scheme for the active auxiliary circuit to stabilize the system and mitigate the load transients. In the proposed control scheme, two band-pass filters are introduced to make the active auxiliary circuit operate at two specific frequency bands. The simulation results are shown to validate the proposed control scheme.
