The invention provides a wheeltrack train eddy current braking device under the condition of no electricity of a pantograph net and a control method of the wheeltrack train eddy current braking device. The permanent magnet traction motor is connected with the traction converter; one end of the eddy current braking power supply device is connected to a connecting line of the traction converter and the traction converter; the eddy current excitation coil is connected with the other end of the eddy current braking power supply device; the train power distribution system is connected with the traction converter and the eddy current braking power supply device; and under the condition that the bow net of the wheel-rail train has no power and emergency braking needs to be carried out, the train power distribution system sends an eddy current braking instruction to the traction converter and the eddy current braking power supply device, so that the traction converter is isolated from the permanent magnet traction motor, and the eddy current braking power supply device is communicated with the permanent magnet traction motor. The problem that the electric braking force cannot be provided for the wheel-rail train under the condition that the pantograph net has no electricity is solved, the emergency braking distance is reduced, and the running safety of the train is ensured.
