Dynamic Controller Based Linear Quadratic Optimal Control for Stabilization of Zero-Voltage-Switching Buck DC/DC Converters

Abstract:

DC/DC converters are known to exhibit bifurcations and chaos if switching actions are governed by feedback control. A dynamic controller based optimal control method is presented to control the chaos behavior and maximize the conversion efficiency of a zero-voltage-switching (ZVS) buck converter operating in continuous conduction mode (CCM). The simulation results show the effectiveness of the proposed scheme.
