Abstract

Multiple-input dc/dc converters are widely used in hybrid power systems which normally derive power simultaneously from several renewable energy sources and deliver power continuously to the load. Due to intermittent features of the available energy from the renewable sources, such multiple-input conversion systems are often designed with multiple structures and multiple operating modes, and their dynamic behavior is thus quite complex. We consider a hybrid power system with the dual-input buck converter as its constituent system. We study the dynamic behavior of this system and reveal the smooth and non-smooth bifurcation phenomena with low-frequency oscillation. Moreover, a detailed analysis based on an averaged model is performed to identify the two types of bifurcation and evaluate the stability boundaries of the system.
