| Abstract |
This paper presents research motivated by industrial demand for special traction drive topology devoted to minimization of traction transformer weight against topology with classical 50Hz traction transformer. The main attention has been given to the special traction drive topology for AC power systems: input high voltage trolley converter (single phase matrix converter) - middle frequency transformer - output converter (single phase voltage-source active rectifier + three phase voltage-source inverter) - traction motor. The control algorithm (Inserting of NULL vector of matrix converter, Two-value control of secondary active rectifier, PWM and etc.) of innovative traction topology with middle-frequency transformer has been described. |
