The invention discloses a suspension controller of a magnetic suspension train, which comprises a box body and electric elements such as insulated gate bipolar transistor (IGBT), wherein the box body is cast by using an aluminum material, and the bottom of the box body is provided with radiation fins; a main circuit input end protective fuse and a control circuit input end protective fuse are arranged on an insulation board to form an insulation board component; a supported capacitor and a wiring terminal are mounted on an aluminum mounting board to form a mounting board component; and a current sensor, a voltage sensor circuit board, an output filter reactor, a charging resistor and a discharging resistor are mounted on the bottom face of an 'L'-shaped mounting board, a charging contact and a main contact are mounted on the side face of the 'L'-shaped mounting board, and thus, an 'L'-shaped mounting board component is formed. In the invention, the heating electric elements such as the IGBT are mounted on the bottom face of the box body and the heat of the electric elements can be dissipated by the box body, so it is unnecessary to configure a special radiator for the IGBT with the box body as the radiator; and thus, space is saved, and the suspension controller meets requirements on electrical performance as well as size and weight.
Description
technical field [0001] The invention relates to a current conversion device for providing suspension, guidance and traction for a magnetic levitation train, in particular to a levitation controller for the magnetic levitation train. Background technique [0002] The maglev train realizes levitation, guidance and traction through the electromagnetic conversion of the inductance coil, so it needs to provide a constant current power supply for the inductance coil, and the levitation controller is the current conversion device that provides power for it. Since the operation of the maglev train requires several independently powered inductance coils, many levitation controllers need to be installed in each carriage, which requires the size of each levitation controller to be reduced as much as possible. It is now required that its external dimensions be 1020mm×270mm×255mm, and that the power of the suspension controller stand-alone be 40kVA and the weight less than 40kg. The req...
