Modelling switched mode DC-DC converter using system identification techniques: A review

Multi converter based distributed power system (DPS) comprises of several interconnected switched mode power converters. The large scale implementation of DPS in variety of applications has provided new research directions in modeling and control of switched mode power converter. With evolution of DPS, black box, grey box modeling and identification of converter dynamics holds a significant research interest. A large number of papers study the identification aspect as well as real time implementation of identification techniques in switched mode power converter. Therefore, a proper review of available identification methods is the need of the day. In this paper, comprehensive reviews of parametric and non-parametric identification techniques of switched mode power converter have been discussed. This paper is intended to serve as a reference towards identification aspect of switched mode power converter.
