ABSTRACT:
Four sets of a first pair of diodes, a second pair of diodes and a GTO breaker are connected between the power rectifier, the power inverter and four electric car power supply lines arranged in parallel with each other and separated by two dead sections. Therefore, it is possible to cut off powering current and regenerative current simultaneously by simply turning off the GTO breaker. Further, even if a regenerative electric car is running on the electric car power supply lines, it is posible to prevent the occurrence of an arc at the other dead sections due to a potential difference between two power supply lines. Further, in case of powering/regenerative bus bar accident, it is possible to effectively cut off both a regenerative current and an extension power supply current flowing from the power supply lines by the four GTO breakers of a relatively small interrupt capability without exerting the influence of power suspension upon other adjacent substations supplying the extension power supply current.
