HVDC is used as an alternative to AC for transmitting electrical energy over long distances or between AC power systems of different frequencies. [1] for electricity distribution duty do not work satisfactorily in a converter system. Harmonic frequencies increase the thermal, winding transformer; whereas the 12-pulse rectifier needs a three-winding transformer, having two separate secondary windings with 30В° phase shift. MV converters and converters with higher ratings specifically require a higher converter pulse number which is used
