Propulsion converter for electric multiple unit


KONTRAC GP550AC converts the power from transformer outputs of AC network into propulsion power for the traction motors. It has sinusoidal input current in phase with voltage and with low harmonic content. During braking, the converter feeds back energy to the network. All control, protective, communication and monitoring functions are implemented in one control electronics inside the converter.
