Circuit Characteristic Research Of Electrodeless Lamps Based On Chaotic Theory

Chaotic phenomenon is an inherent form of motion in nonlinear circuits.When chaos occurs,it will affect the stability of the system.Therefore,in order to avoid,control and use chaos better,it is necessary to fully understand the chaotic behavior and chaos formation of chaotic system mechanism.Switching converter as a widely used with non-linear characteristics of the circuit,has now become a research hot research at home and abroad.Based on the chaos theory,this paper analyzes the chaotic dynamics of the switching converter and simulink simulation of the boost converter which satisfies the requirements of the electrodeless lamp.Firstly,the traditional chaotic analysis method is used to analyze the typical chaotic circuit,and the chaos theory is used to analyze the advantages of the nonlinear circuit from the verification of the characteristics of the typical chaotic circuit.And the introduction of the electrodeless lamp circuit as a whole,the non-linear part of the electrodeless lamp circuit is extracted,that is,the booster circuit.Secondly,the chaos theory is used to analyze the chaotic behavior of the switching converter.Based on the traditional entropy theory,the multi-scale entropy theory is proposed.The chaos analysis of the DCM Buck converter is used to verify its correctness and feasibility.Then,the multi-scale entropy theory is applied to the DCM Boost converter,and the chaotic characteristics of the system are analyzed and compared with the traditional entropy theory of information entropy and relative entropy Compared with some new entropy theories,the multi-scale entropy theory contains few factors,and the experimental results are more.In addition,the multi-scale entropy theory is different from the first two kinds of analysis methods.objective.The multi-scale entropy can distinguish the working state of the system,and the size of the multi-scale entropy of the system increases with the increase of the feedback parameter,which is independent of the initial value of the system.Secondly,the discrete model of Boost converter in CCM mode is proposed,and an adjacent data dependency analysis method is proposed.Combined with the system phase diagram generated by CCM mode,the sensitivity of system chaos to different parameters is analyzed.Finally,the Boost converter is simulated by Simulink,and the influence of the boost inductor and the energy storage capacitor on the system,output is analyzed.The boost inductor determines the size of the output voltage more,and the energy storage inductance more affectes the ripple voltage of the circuit and the time reach to the steady state.The research on the relationship between the performance of the boost circuit and the parameters of the circuit provides a theoretical basis for the selection of the parameters of the electrodeless lamp booster circuit.
