Abstract
In-depth analysis of the complex nature of the circuit, this paper discussed chaotic dynamics theory. The numerical simulation of power electronic circuits gives the complex dynamic behavior of the circuit. By theoretical analysis, to explore the root causes of the phenomenon, and through specific circuit experiment. Kinetic behavior of complex present in the circuit for establishing the corresponding chaos control method, we try to keep the original circuit structure and parameters on the basis of the system. It has excellent working stability studies which obtained the outcome. They will be a variety of power electronic circuits provide important theoretical guidance. Analyzes the general chaotic dynamical systems, in terms of the history of the development of chaos, chaos characteristics of the roads leading to chaos, chaos theory describes nonlinear systems related. Lists typical continuous dynamical systems and chaos typical discrete chaotic system dynamics, and specific analysis for studying complex phenomena of power electronic circuits provide a theoretical basis.
