The AFE consists of three identical phase modules, each housing the HV
IGBT (Insulated Gate Bipolar Transistor) semiconductors, phase
capacitors, gate drivers and the interface board for communication with
the circuit board of the AFE (AMC circuit board).
The high voltage IGBT is a power semiconductor switching device
specially developed for medium voltage drives. The device combines high
speed switching capabilities with high blocking voltage and low conduction
losses.
The phase modules can be removed from the cabinet for maintenance
and service.
