Abstract

In order to improve electromagnetic compatibility and deduce ripple of output voltage of the voltage-programmed buck converter, a state-feedback method with saw-tooth wave function to make this circuit system chaotic are proposed. The effectiveness and correction are proved by numerical simulation. Furthermore, in order to analyze physics mechanics from theory about reducing ripple of output voltage of the controlled circuit system, discrete map model of the converter operating at chaos is built. Nonlinear dynamical behaviors are analyzed by this map model, and operational mechanics about deducing ripple by control parameters is illuminated.
