Title:
POWER CONVERSION DEVICE FOR RAILROAD CAR
Document Type and Number:
WIPO Patent Application WO/2024/009361
Kind Code:
A1
Abstract:
In this power conversion device for a railroad car, a main conversion device (105) comprises a converter (210), a smoothing capacitor (220), and an inverter (230). The converter (210) operates so as to make a capacitor voltage that is the voltage of the smoothing capacitor (220) constant during a power supply period in which power is supplied from an aerial line (100), and operates to supply regenerated power generated by a propulsion motor (106) to an auxiliary power supply device (107) through a main transformer (104) in a non-power supply period in which the supply of power from the aerial line (100) is not performed. The inverter (230) outputs a drive torque for driving the propulsion motor (106) in the power supply period, and operates in accordance with a target value of the regeneration power determined on the basis of required power for auxiliary equipment in the non-power supply period.
