Description
Sensing PCB (EPS476), big cabinet
The sensing PCB measures the AC input line and controls the
diode bridge.
IGBT, all cabinets
An IGBT controls a high power via a low power electronic signal.
The IGBT can switch at high frequency.
Two IGBTs are installed together in one housing.
The system uses four IGBTs connected as an H-bridge to make
an AC-signal.
IGBT PCB (EPS477 / EPS496 / EPS 478), all cabinets
The IGBT PCB measures the output signal from the IGBT H-
bridge.
Note
In the big cabinet, the sensing PCB and the diode
bridge are separate parts.
