Abstract: In this paper we consider a modified model of an Alpazur oscillator with a periodically switching operation. Complex oscillatory phenomena are observed due to both switching operation and the appearance of an additional nonlinear component in circuit model. Indeed, subharmonic oscillations and chaotic behavior are illustrated. In addition, time series, phase trajectories and power spectrum was examined in the analysis of the system dynamics. The transition to chaotic states through doubling period bifurcation cascade and the direct transition from fundamental harmonic or odd subharmonic orbits and transition from a special bifurcation paths to chaotic states are discussed in the state space. The role of higher harmonic spectral lines in period-1 responses under parameter variation have seemingly similarities with the results obtained in previous works for non switched dynamical system. Chaotic states resulting from different transition modes are also presented in t!
his paper. For the numerical simulations, techniques for deriving time and composite Poincar´e method are applied.
Keywords: Switching operation,Transition modes, higher harmonic predominance, doubling period cascade.
