The ACS 5000 protection scheme
responds less than psec, about two
hundred times faster than fuses.
Long-life DC-link capacitors
Advanced, self-healing, environmental friendly
foil capacitors, designed for long lifetime,
are used the DC-link.
Fuseless
The converter design does not require any
m edium voltage pow fuses, hich are
known unreliable, costly and subject
to aging.
The use IGCTs results low parts count,
providing intrinsically less complex, ore
efficient and reliable drive. ABB has clearly
distinguished itself with this technology
com pared unreliable and aintenance
intensive designs based electrolytic DC-link
capacitors.
Converter with integrated input transformer
ACS 5000 Voltage Source Inverter Multilevel-Fuseless (VSI-MF) topology
4 ACS 5000 ABB
.ACS 5000 Highest performance and lowest cost ownership
ABB engineers developed drive that provides advantages over other medium
voltage drives reliability, efficiency and power density features that have a
direct impact the customer’s cost ownership. Instead fuses the ACS 5000 uses
IGCTs/thyristors, which provide much faster
and more reliable protection for the power
components.
Highest reliability and efficiency
Thanks the combination well-proven
com ponents and innovative topology,
the ACS 5000 has reliability and efficiency
unmatched the market.
IGCT semiconductors
The ACS 5000 uses advanced and proven
pow sem iconductor itching device
known IGCT. combines the best two
traditional semiconductor technologies: the fast
switching the IGBT/IEGT with the proven
reliability and low losses the GTO
