Development of Inverter for Regenerative Power and Test Equipment

직류급전시스템 회생용 인버터의 시험설비 구축 및 특성시험

DC transit system has been adopted in the metropolitan area, Korea since 1974. EMU in this system always reiterates that acceleration and retardation. When EMU decelerates using electric breaking, regenerative power occurs. Regenerative power can be consumed in vicinity EMU on the same line or in resistor. If DC transit system has inverter for reusing regenerative power, Energy efficiency in DC transit system will be increased. This paper present the developed inverter for regenerative power and its test equipment. Test result of developed inverter is presented.
