Stabilizing the Nonlinear Dynamic Behavior of LLC Resonance Full-Bridge DC-DC Converter Under Voltage Mode Control
In this paper, a simple control method is presented to stabilize the nonlinear dynamic behavior of LLC resonance full-bridge DC-DC converter under voltage mode control based on the conventional delay time feedback, resonant parametric perturbation and self-stable control methods. First, the mathematical model of LLC resonance full-bridge DC-DC converter under voltage mode control are built. Second, the dynamic behaviors of the system is analyzed and the system is lost stability by border collision and Neimark-Saker bifurcation. Finally, the simple controller is introduced by sampling the primary inductor current of the transformer, and then the simulation results show that the dynamic behaviors can be stabilized by this controller.
