DC link available in terminals for
common DC configurations

Simple way to implement low

Comparison to thyristor bridge
Motoring
bridge
© Copyright year ABB - 34 -
If thyristor bridge is regenerating
and line voltage drops, a
thyristor cannot interrupt the
current. The current can rush
and blow the fuses. This is also
risk for components.
IGBT is able to switch off the
current and protect the
components. Control can
function even during voltage dip.

In low network voltage
conditions motor still gets full
