Title: Power supply circuit system and feeder system of electric vehicle
Inventor: WATANABE HIDEO
IPC: B60L5/00
Filed: 2001-06-05
Abstract: PROBLEM TO BE SOLVED: To pass an electric vehicle through a dead section while powering. SOLUTION: In power supply circuits of electric vehicles 10a and 10b for driving induction motors 181 -184 by converting AC power from a pantograph 11 through converters 161 -164 into DC power and then inverting the DC power through VVVF inverters 171 and 172 into AC three-phase power, the converters 161 -164 of both electric vehicles in the power supply system of the pantograph thereof are connected in parallel through cables 21a and 21b on the output side (DC power supply system). When one electric vehicle enters a dead section 2 while powering, it can pass through the dead section 2 while powering because the inverter of that electric vehicle operates using the converter output of the other electric vehicle as a power supply. When the electric vehicles 10a and 10b enter the trolley wires 171 and 172 of different power supplies, they can travel with the power from the trolley wires 171 and 172 without short-circuiting them because the pantographs 11 of both electric vehicles are not connected to the cables.
