ELECTRIC POWER SUPPLY DEVICE FOR RAIL CAR EQUIPMENT Russian patent published in 2021 - IPC B61D43/00 B61L1/02 H02K35/04 

FIELD: railroad industry.

SUBSTANCE: invention relates to devices that use vehicle motion energy, and can be used in train traffic control systems for powering railroad automation electronic devices. The power supply device for the equipment of rail cars is formed by a wheel base with two wheels mechanically connected to each other by an axle and running on the first and second rails of a rail track, and the electronic equipment of the rail car. The electronic equipment of a rail car contains an electric energy storage device connected in parallel to the outputs of the rectifier and in parallel to the power supply inputs of electronic devices. A permanent magnet is installed between the rail webs. On the axis of the wheel base a non-magnetic cylinder is installed with a gap, on which an inductor is wound, the terminals of which are connected to the inputs of the rectifier, the outputs of which are connected through the electric energy storage unit to the supply input of the car’s electronic devices.

EFFECT: increased reliability and durability of the power supply device.
