Bifurcation diagrams with the input voltage as the variable parameter have been obtained. The experimental results show that the converter shifts between period one, period two, higher periods and chaos as the parameter is varied. The bifurcation phenomena have been reported.

Because the approach avoids averaging and approximations related to this process, a very good accuracy of the derived model is obtained. The main difference between the presented approach and the existing methodology for accurately predicting the behavior of switching converters is that, here, we break the feedback loop and we focus on analyzing the open‐loop gain and the effect of the system parameters on relative stability. This results in an approach much similar to control systems techniques rather than nonlinear dynamical system approaches. Consequently, the relative stability is tackled easily in the frequency domain. In particular, by treating the modulator as a gain depen...
