ACA 635 IGBT Supply Sections
The synchronization parameters are listed below.
Starting Sequence
During the charging procedure the main contactor is closed, and after
the synchronization routine is completed, the modulator is started and
the ISU runs normally.
A simplified block diagram of the modulator starting (from starting
switch on the cabinet door or via fieldbus) is presented below. For
description of the starting procedure see the next pages.
