Reduction of EMI using Anticontrol of Chaos
Résumé
DC-DC converters are employed in various electrical devices, thus forming main sources of electromagnetic interference (EMI). By making the DC-DC converter operating in chaos, using a new nonlinear feedback controller, the simulation results illustrate that a reduction of spectral peak and consequent spreading of the spectrum can be shown. This simple strategy not only improves the electromagnetic compatibility of the converter, but also reduces the output voltage ripple. A Power System Blockset (PSB) model using Simulink/Matlab is designed and results are compared to those obtained with the classical anticontrol method.
