Due to advantages of high efficiency simple topology and easy implementation the DC/DC converter has been widely used in a variety of electrical fields. The stability of power electronic systems and the reliability power electronic systems are the fundamental requirements for electrical system operation. However, there may exist complex nonlinear phenomena in the DC/DC converter systems, which will induce the instability or failure of the electrical systems. Therefore, the research topic of nonlinear dynamics in DC/DC converters has attracted much attention. Memristor, as the fourth generation electrical device, has been applied in multiple electrical circuits. Researching on the nonlinear phenomena of DC/DC converter with memristor load has becoming a hot topic in recent years. Although many nonlinear phenomena in different DC/DC converter structures with memristor load has studied in previously works, the phenomenon of coexisting attractor, which reflects the influence of initial states on memristive electrical system has not been reported. In this work, we studied the nonlinear dynamics of a voltage controlled buck converter with memristor load. The bi-stable coexisting attractor phenomenon is found in the memristive buck converter for the first time.
