Abstract: Switching converter circuits are nonlinear and time-varying in nature. In this paper, the complex dynamics in voltage mode controlled (VMC) DC-DC boost converter has been investigated through simulation and experimentation. The converter is controlled by naturally sampled constant frequency pulse width modulation (PWM) signals in continuous conduction mode (CCM) and converter exhibits fundamental, quasi-periodic and chaotic oscillations for the variation of circuit parameters. In simulation study, the model of boost converter is computed by non-autonomous differential equations and finally, the computational waveforms have been verified with experimental results. In order to verify simulation study, a laboratory scale prototype of closed-loop boost converter has been fabricated. The closed-loop converter is controlled by dSPACE in real-time platform. The results obtained from simulation and experimental study have been presented and compared. It has been observed that the route to chaos is achieved by the slow-scale instability in this proposed study.
