Modeling and analysis of dynamic properties of the hybrid transformer with MRC

Abstract

this paper deals with the modelling and analysis of dynamic properties of the three-phase AC transformer with electromagnetic and electric (hybrid) coupling. The electromagnetic coupling is realized by means of the conventional transformer. The electrical coupling is realized by means of a matrix-reactance chopper (MRC), which is supplied from an auxiliary secondary winding of the transformer. In this paper there are descriptions of the proposed solution, with a presentation of their modeling and analysis of their dynamic properties.
