Abstract

The system under study consists of two Cuk converters operating under free-running current-mode control, with the two converters connected in the well known drive-response configuration similar to that studied by Pecora and Carroll (1991). This paper investigates the synchronization property of the system when a capacitor voltage is chosen as the driving signal. The study includes the derivation of the describing differential equations and the calculation of the conditional Lyapunov exponents (CLE) of the synchronizing system based on the differential equations. It is found that all the CLEs are negative for certain chosen parameters, and hence synchronization is possible in this system. “Exact” computer simulations have been performed to verify the synchronization of the afore-described circuits operating in a chaotic regime
