Control algorithms for traction drive with high voltage matrix converters and medium frequency transformer

This paper describes the control algorithms for electric drive with single phase matrix converters supplied medium frequency converter for traction purpose. Described control algorithms realize the control of active and reactive power, output voltage, reduce harmonic disturbance in input current and oscillation of voltage on input filter etc. These control algorithms were implemented into multiprocessor control system with DSP for small-scale prototype as physical model in laboratory.
