When the ventilation inverter (ventilation inverter, VTI) of high-speed rolling stock normally receives power supply from stringing, it receives power from supplementary power device and supplies power to the ventilation fan. At this point, entry to neutral section blocks regeneration, burning the regeneration energy through resistance. Using a tap of resistance as VTI power at this point receives and converts input of rough electricity, causing consistent breakdown of VTI and ultimately leading to stop in operation. Also, entry to neutral point activates the chopper, burning energy through resistance. Switching the location of resistance and chopper solves many aspects, but it does not solve fundamental problems. As a result, this study solves the fundamental problem of VTI by installing DC/DC converter that receives input of DC Link 2800[V] and converts it into 670[V] when entry to neutral point occurs, enabling stable power supply.
