METHOD OF ADJUSTING DIESEL LOCOMOTIVE ADDITIONAL AC GENERATOR VOLTAGE Russian patent published in 2010 - IPC B60L1/00 H02P9/08 

FIELD: transport.

SUBSTANCE: invention relates to railroad transport, namely to locomotive traction circuitry. Proposed method consists in that diesel locomotive onboard circuit fed from storage battery is connected to voltage pulse-width control system. Voltage from output of said system is fed to input of AC additional generator excitation winding via current limiting unit. Voltage from AC additional generator power winding output is fed to locomotive onboard circuit via uncontrolled bridge rectifier. Onboard circuit voltage is measured and normalised. Voltage signal, as-measured and normalised by voltage transducer, is sent to one input of comparator unit. Onboard circuit voltage setting is set by voltage setting unit. Signal from voltage setting unit output is fed to another input of comparator unit. Said setting is compared with measured and normalised values. Results of comparison is fed to input of voltage pulse-width control unit. Current in excitation winding is regulated. Diesel locomotive onboard circuit is adjusted. Voltage is fed to input of AC additional generator excitation winding.

EFFECT: simplified voltage control.
