Phase module
—
References
The AFE consists of three identical phase modules
—
each housing the series-connected IGBT semicon-
2-6 Phase module
ductors, the phase capacitor, the gate drivers, and
the interface board for communication with the
main control circuit board (AMC circuit board) of
the AFE.
The high voltage IGBT is a power semiconductor
switching device specially developed for medium
voltage drives. The device is based on well-estab-
lished transistor technology and combines high
speed switching capabilities with high blocking
voltage and low conduction losses as known from
GTOs.
