title = "Dynamic response enhancement of cascaded DC/DC converter systems using an auxiliary circuit",
abstract = "The paper presents an approach to enhancing the dynamic response of a cascaded DC/DC converter system, where virtual impedance control schemes are used for stabilization. A cascaded DC/DC converter system may not be stable when the source and load converters are not designed appropriately. Such system can be stabilized by reshaping the input impedance of the load converter with the virtual impedance control method. However, the dynamic performance suffers due to the added virtual-impedance control loop. In this paper, the dynamic performance of the cascaded DC/DC converter system is enhanced with an additional auxiliary circuit that is connected to the output port of the load converter and functions to buffer fast load transients. The simulation result shows that the voltage transient deviation on the load converter is significantly reduced with the proposed method.",
