Abstract:
This paper is concerned with themodelling of a DC-DC boost converter, operating in discontinuous conduction mode (DCM). The approach chosen is to model the converter using a state-dependent parameter (SDP) model approach which is expected to be able to deal with the nonlinearities of the system, as well as a varying load. The modelling procedure presented, makes use of input-output data only and no physical insight into the system is required. Results are verified via laboratory experiments.
