Study on the Dynamical Model and Analytical Methods for DC-DC Switching Converters

Abstract

DC-DC converters are the kernel parts in the switching power supplies. There are abundant dynamical behaviors in them. In order to discover all these linear and nonlinear phenomena it is demanded to put forward some appropriate modeling methods. Discuss the modeling methods which aimed at some familiar DC-DC converters under the control of voltage and current mode. They include exact simulation model and discrete map. All results are brought with experiments. The study methods and process are suitable to the other converters which under the control of voltage or current mode.
