- Abstract:
-
The level of electromagnetic interference (EMI) is related to the application of switch-mode power supply, and reducing the electromagnetic interference (EMI) level of switch-mode power supply is a hot issue in current research. Starting from the inherent chaotic phenomenon in switch-mode power converters, the idea of applying parameter combination control to change the working state to reduce the level of electromagnetic interference is proposed. Furthermore, the DC/DC Boost converter was used as the object to carry out computer simulation analysis. By adjusting the size of the parameters Iref, k and Vref, the transformer runs in periodic, quasi-periodic and chaotic modes, respectively. The simulation results show that the electromagnetic interference level of switch-mode power supply can be reduced without attaching any peripheral circuits by using the inherent chaos phenomenon in the switch-mode power supply.
