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.
Highest reliability and efficiency
Thanks the combination well-proven
com ponents and innovative topology,
the ACS 5000 has reliability and efficiency
unmatched the market. combines the best two
traditional semiconductor technologies: the fast
switching the IGBT/IEGT with the proven
reliability and low losses the GTO.
IGCT semiconductors
The ACS 5000 uses advanced and proven
pow sem iconductor itching device
known IGCT. ABB has clearly
distinguished itself with this technology
com pared unreliable and aintenance
intensive designs based electrolytic DC-link
capacitors.

Long-life DC-link capacitors
Advanced, self-healing, environmental friendly
foil capacitors, designed for long lifetime,
are used the DC-link. The ACS 5000 protection scheme
responds less than psec, about two
hundred times faster than fuses. Instead fuses the ACS 5000 uses
IGCTs/thyristors, which provide much faster
and more reliable protection for the power
components.
The use IGCTs results low parts count,
providing intrinsically less complex, ore
efficient and reliable drive
