Fuseless
The converter design does not require any
medium voltage power fuses, which are
known unreliable, costly and subject
to aging. Advanced, environmental friendly,
rapeseed oil-filled foil capacitors, designed for
a long lifetime, are used instead.
Powerful motor control platform
The motor control platform the ACS 1000
drives family BB’s award-winning Direct
Torque Control provides rapid,
accurate and stepless control from zero full
speed and can deliver full torque with optimal
speed accuracy over the whole speed range,
even without encoder. combines the best of
two traditional semiconductor technologies:
the fast switching the IGBT with the
proven reliability the GTO.Reliable and efficient components
Reliable components
IGCT semiconductors
The ACS 1000 and ACS 1000i use power
sem iconductor known IGCT (Integrated
Gate Commutated Thyristor), which the
ideal switch for high-pow ered medium
voltage applications. The ACS 1000 and ACS 1000i use
dedicated IGCTs, instead, hich provide
faster and better protection for the power
components.
Long-life capacitors
Electrolytic capacitors, which have poor life
expectancy, are not used the ACS 1000 and
ACS 1000i.
Power loss RideThrough
A special feature DTC its ability ride
through short main supply voltage interruptions
so that most cases the process not affected.
Medium Voltage
Supply Bus
ACS 10OOi converter with integrated input transformer
The ACS 1000 drives family’s well proven three-level inverter, without series parallel connected power
semiconductors, one the least complex, most robust and efficient drive topologies. The use of
IGCTs results low parts count, providing
an efficient and reliable drive.
