Abstract

Chaotic chattering behaviors of DC-DC converters are caused by the nonlinearity of the switching operation which is an. essential characteristic of the power electronics circuits. In this paper the bifurcation and the appearance of the chaotic chattering in the discontinuous current conduction mode of a DC-DC buck converter are discussed experimentally. Moreover, a method for controlling chaotic chattering behavior is proposed in. the discontinuous current conduction node using delayed feedback in a discrete system. The possibility of restricting the chaotic chattering is confirmed
