METHOD FOR POWER SUPPLY IN A TRACTION NETWORK WITH CONTACTLESS TRANSMISSION OF POWER TO ELECTRIC LOCOMOTIVES

摘要

The proposed method for power supply in a traction network with contactless transmission of power to electric locomotives is distinctive by that that frequency-modulated current pulses in the traction network are used. The length of the current pulse does not exceed the tenfold time of transition in the traction network. According to the present invention, the length of the current pulses is constant and corresponds to the minimal load of the traction network. The output voltage of the network would be maintained to be constant, if the load of the traction network varies, by controlling the current pulse period.
