A device of the contactless electric power supply of transportation means contains a power source with pulse shaper, a tractive circuit and an energy-receiver inductively connected with it which is made from magnetic circuit and two windings, the first of which feeds electric drive, and the second is connected to the capacitor forming with it an oscillating circuit. Furthermore, the magnetic circuit of electrical receiver is made with transverse cross connection on which the second winding is placed, and into the electrical circles the switch at the inlet of tractive network, the adjustable switch at the inlet of the first winding, the regulator of the period of power supply pulse advancing,the discharge resistor and the voltage sensor which are connected mutually in parallel are introduced; moreover the mentioned switch is made with possibility of the start of the circuit of tractive network at the end of the action of each pulse of power supply on the discharge resistor and the voltage sensor, where the latter is connected to the inlet of the regulator of the period of power supply pulse advancing, and the adjustable switch is made with possibility of connection of the first winding to the electric drive for the period of the pause between adjacent power supply pulses.
