Exciter device for the onboard power generator of the Vossloh DE18 locomotive

Überblick

An exciter designed for the onboard power generator of the Vosslow DE18 locomotive with a three-phase excitation winding.

This device consists of a controlled 3-phase frequency converter that is supplied directly from the starter battery. There are two operating modes for the machine: when motoring, the excitation is necessary starting the diesel generator, and when generating, the DC-link voltage of the downstream converter is controlled.


Characteristics

Rated voltage: 110 V DC … 180 V DC

Over-voltage turn off: 188 V DC
