FIELD CURRENT REGULATING DEVICE FOR SERIES-WOUND MOTOR Russian patent published in 2000 - IPC

Abstract RU 2155436 C1

FIELD: electrical engineering; DC traction motors. SUBSTANCE: device that has electronic switch whose positive terminal lead is connected to one lead of field winding and negative one, to other lead of field winding, as well as shunt resistor connected in parallel with electronic switch is provided, in addition, with diode inserted between positive lead of electronic switch and shunt resistor lead; diode cathode is connected to resistor and capacitor is connected in parallel with shunt resistor. Maximum voltage across electronic switch is reduced. EFFECT: improved stability and reliability of electronic switch. 3 dwg
