NEW control algorithm for traction drive with single phase Matrix converter

This paper presents research motivated by industrial demand for special traction drive topology devoted to minimization of traction transformer weight against topology with classical 50 Hz traction transformer. The main attention has been given to the control strategy of the special traction drive topology for AC power systems. The proposed converter control algorithm of innovative traction topology with middle-frequency transformer has been described in detail. The theoretical conclusions and simulation results are compared with experimental measurements on laboratory model with rated power of 4 kVA.
