Abstract
In the paper presented the model of the voltage inverter type DC/AC used in modernized electrical traction. In this inverter, the SVPWM (Space Vector Pulse Width Modulation) control method was used which allow to the accurately imitate the voltage sinusoidal variable waveforms on its output connectors. The circuit of this type working in overhead contact line generates pulsations of input-current at a frequency six times higher than the frequency of its output voltage. At the DC input of the inverter circuit in the electric traction rail, the load current of the mains network is monitored. to determine the electricity consumed by the traction unit.
