DYNAMIC MODEL OF MODULAR DC-DC CONVERTER WITH THREE DUAL ACTIVE BRIDGE CONVERTERS WITH SERIES INPUT PARALLEL OUTPUT CONNECTIONS
Journal Title: Proceedings of Electrotechnical Institute Prace Instytutu Elektrotechniki - Year 2016, Vol 63, Issue 275
Abstract
This paper describes the results of the analysis of the dynamic model of a multi-modular DC-DC converter, consisting of double active bridges DAB. The considered topology has a series-connected high-voltage terminals and low-voltage terminals connected in parallel. On the basis of the circuit model of the DAB, averaged dynamic model in the form of a transfer function has been developed, using tools available in the System Identification Toolbox in Matlab. Using this software, the parameters of PI regulators in closed loop control were tuned, providing adequate dynamic properties and maintaining the stability of the system.
