Inventor: OTA YUKIO
IPC: H02J1/00
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To increase the overall efficiency of a motive power/feeder plant and to reduce the quantity of power consumption by feeding received power from an aerial line and the charged power of a battery to a motor circuit, and preventing the charged power and regenerative power from flowing back to the aerial line by interruption with a diode. SOLUTION: Power is received by a collector 2 touching an aerial line 1, and is connected in parallel with each power unit of adjoining coupled cars by an electric wire 3. Besides, a power receiving circuit is composed of a circuit- breaker 4 and a counter flow preventing diode 5, and is connected to the main circuit of a motor via a chopper 6, a reactor 7, a current detector 8, and contractors 9, 10, 11. And, in the cource of a stop or going at a low speed, a battery 12 is charged when the aerial line 1 is not loaded or is lightly-loaded and the power voltage received is high. And if the voltage drops because of a heavy load such as starting, acceleration, etc., of a contiguous car, the diode 5 of the power receiving circuit prevents counter flow, so the voltage of the battery is kept at the rated voltage of the aerial line 1 or higher.  Besides, a reactor suppresses an instantaneous inrush current of the battery 12, and the chopper limits the current.
