Abstract: Boost converter is one of the most used DC/DC converters, in which there are more chaotic phenomena to make system work unsteadily. Based on the need to select the parameter to control chaos in Boost converters, the circuit model and discrete equations in continuous conduction mode are built, and working range is also deduced. The sensitivity of chaos behaviors to various kinds of parameters, such as current amplifying factor, input voltage, output voltage, boost induc- tance and switching period, are analyzed in detail with digital simulation and practical application, and then provide the design foundation for suppressing chaos with small parameter perturbation.
