Propulsion control device for high speed train of DC link sharing type

摘要

The present invention discloses a propulsion controller for a DC link shared type high-speed train. The present invention comprises a plurality of inverters of a propulsion control apparatus for a high-speed train, -) stages, or the input / output terminals of the power stacks included in the plurality of inverter sections sharing the (+) terminal or the (-) terminal of the DC link are arranged in parallel, In particular, when the power circuit of the propulsion control device is operated by phase, the power stack of the modular IGBT is doubled in the inverter so that individual control of the plurality of motors can be effectively performed, The inverter is made up of one inverter through the extension of the inverter, so that a plurality of motors can be driven in parallel. The performance of the control device is improved.
