Solid state modulators based on pulse transformer offer the advantage, that with the turns ratio of the transformer, the primary voltage ideally could be adapted to the available switch technology and a series connection of switches could be avoided. For increasing the power level several semiconductor switches must be connected in parallel and a balancing between the different switches must be guaranteed. There, the Matrix Transformer concept, which is based on multiple primary and/or secondary windings as well as on flux adding, offers superior performance with respect to the achievable rise times. However, the influence of the parasitic elements on the voltage and current distribution is quite involved. In this paper the influence of the parasitic elements of the Matrix Transformer on the current balancing and winding voltages is investigated based on reluctance models and the inherent current balancing of the Matrix Transformer for windings mounted on different cores is explained. Furthermore, the influence of parasitic load/transformer capacitances on the turn-off transient is discussed in detail. Show more
