摘要

A direct-current-dorect-current (DC-DC)buck converter with integrated load current feedback is studied with three kinds of Poicaré maps.The external corner-collision bifurcation occurs when the crossing number per period varies,and the internal corner-collision bifurcations occur along with period-doubling and period-tripling bifurcations in this model.The multi-band chaos roots in external corner-collision bifurcation and often grows into l-band chaos.A new kind of chaotic sliding orbits,which is more complex for non-smooth systems,is also found in this model.
