ABSTRACT:
A circuit device is disclosed which is used to increase useable motor voltage in a long stator drive. Further, suitable methods for operating a magnetically levitated vehicle provided with the circuit device are also disclosed. In one embodiment of the present invention, the stator section of the long stator drive is connected to the energy supply line on two connection points by way of a first and a second switch. A third switch is located between both connection points arranged on the energy supply line. Both of the stator section connections are connected to the ground potential by way of a fourth and a fifth switch. In one embodiment, in order to accelerate the magnetically levitated vehicle, the first and the second switches are closed and all other switches are opened. The stator section is cross-flown in a direct manner by current in the energy supply line.
