DC DRIVE Russian patent published in 1999 - IPC

Abstract RU 2130840 C1

FIELD: transport engineering; vehicles supplied from DC circuit. SUBSTANCE: electric drive has DC traction motor with series connected voltage regulator. Voltage regulator is electric circuit consisting of two inverters interconnected by ac terminals through transformer with controlled transformation ratio. Inverters are made for operation as rectifiers. In proposed electric drive current of motor at electrodynamic regenerative braking is transmitted continuously, not by pulses, and continuous excess of effective value of electromotive force above supply circuit voltage is provided. EFFECT: increased efficiency of regenerative energy transmission. 2 cl, 1 dwg
