Phase module
The DC-link capacitor bank is connected to the individual phase modules through a low-
inductance flat busbar. The low-inductance flat busbar is constructed as busbar package. The
individual busbars and insulation layers are glued or screwed together.
3.3.4
Gating
The gating group and the GCT (Gate-Commutated Thyristor) power semiconductor together
form a fixed unit, the IGCT (Integrated Gate-Commutated Thyristor).
The power semiconductors are connected via the gating boards. The gating command is
transmitted from the power stack adapter (PSA) to the gating board via a plastic fiber-optic
cable connection.
3.4
Operating principle
A constant DC-link voltage for the Motor Module is generated from the line voltage. The Motor
Module provides the power for the connected motor via the DC-link voltage.
