The bifurcation behavior a double-input DC–DC buck buck-boost fused converter (DIBBFC) has been discussed in this paper. The considered converter is used to ingrate two different levels of DC voltages for one controlled output voltage. The voltage mode control method is used to obtain desired output voltage while the inductor current is maintained at desired level through the current mode control strategy in this multi-input converter. The discrete mapping of the DIBBFC is established with these two controllers at a time. The limit of reference current is obtained, beyond which the converter has suffered from period-2 and period-4 bifurcation. The theoretical behavior of period-1, period-2, and period-4 state operations is verified by implementing the control in both simulation and real-time environments. The results successfully satisfy the theoretical claim of the bifurcation analysis in both environments.
