A two-dimensional discrete-time map for pulse-width modulated second-order switched-capacitor DC-DC converter is derived.The stability at fixed point of the map is analyzed under nonlinear dynamics theory.The bifurcation diagram and largest Lyapunov exponent graph with the voltage feedback factor as parameter are obtained through numerical computation.Taking second-order switched-capacitor DC-DC converter as an example
we find a chaotic attractor in the converter by simulating the circuit with PSPICE program.The results from theoretical analysis
numerical computation and analog simulation coincide with each other well.
