Abstract It is known that the chaotic behavior could appear in switching-type DC-DC converters, which could not be eliminated by the traditional approach. As the need of network type electrical power system increases, the analysis and control of chaotic behavior become very important issues in converter design. In this.

Moreover, we will also cover the study of AC-DC converters. The proposed works include (i) the study of the dynamic behavior of DC-DC converters: buck, boost and resonant type; (ii) an estimate of the allowed variation range of input supplied voltage and the output power loads without the occurrence of chaotic behavior; (iii) the design of the control laws and the required circuits for the elimination of chaotic behavior in DC-DC converters; (iv) the design of the control laws for guaranteeing the required DC output value of DC-DC converters disregard of input voltage and load change; (v) the study of the nonlinear dynamical behavior and control laws of general single-phase AC-DC converters; (vi) a study of an example three-phase AC-DC converter proposed by Prof. Pan. Keywords: switching-type converter, chaos, bifurcation theory, harmonics, sampled-data method, harmonic balance. 2.
