9 Rectifier and inverter compartment
3.4.6.1. Rectifier
The diode rectifier converts the AC voltage of the main power supply and connects
its output to the minus, neutral point, and plus side of the DC link.
Depending on the harmonics requirements for the main power supply, the drive is
equipped with a 12-pulse or a 24-pulse rectifier.
3.4.6.2. Protection IGCTs
The drive features a fuseless protection design. The IGCTs are placed between the
rectifier and the DC link. If necessary, the IGCTs directly isolate the inverter from
the main power supply.
3.4.6.3. Inverter
The inverter converts the DC voltage to the required AC motor voltage
and frequency.
1) Inverter phase U
2) Inverter phase V
3) Inverter phase W
4) Protection IGCTs
5) Rectifiers
