Summary:
This paper studies nonlinear dynamics of basic dc-dc and ac-dc converters in current mode control. In order to avoid the model becoming too complex, we make the simplifying assumption that voltage regulation is achieved in high frequency modulation and the much slower dynamics of output side can be represented by a constant voltage source. Under this assumption we can derive the 1D return map that describes switching phase of the converters. The map enables us to analyze the dynamics precisely. Typical periodic/chaotic phenomena and related bifurcation phenomena are demonstrated.
