There are many nonlinear phenomena in DC-DC converter because of switching working. These nonlinear characteristics lead to chaos. To optimize parameters and avoid chaos occurring while DC-DC converter working, the analysis of chaos is necessary. But it always focused on simple topology before, because it's difficult to establish a nonlinear mathematic model on complicated DC-DC converter. This paper puts forward a new modeling method with PWM equivalent switching model by analyzing operating characteristic of ZVZCS FB PWM DC-DC converter. This model can be established without solving high order nonlinear equation system. So it makes the modeling course greatly simple, and makes the analysis about chaos in complicated DC-DC converter easily.
