IHV 4500V

We come across 4500 V IGBT modules in our everyday life as they are used to deliver green energy via HVDC transmission lines or they make us move conveniently from A to B in a high speed train. 4.5 kV IGBT modules also find their application in large medium voltage drives making them move with a low energy consumption. But the best part, IHV 4500 V modules can do all of this with the highest reliability and robustness.

Our Industrial High Voltage (IHV) IGBT module in 4500 V come in two different packages:

• IHV A is offering a 10.4 kV isolation capability and the corresponding creepage and clearance distances as required by the harsher environments. The current ratings range from 800 to 1200 A.
• IHV B is cost-optimized for lower demanding applications at sufficient 6.0 kV isolation with current ratings of 800 to 1800 A.

Customer can choose between single switch, chopper or double diode configurations depending on the application requirements.

The well-known market leading IHV 4.5 kV IGBT3 modules have now been upgraded to the latest front- and backend technologies and design possibilities. The FZ1800R45HL4(_S7) feature the latest 4.5 kV chip generation in 8” wafer technology and are the perfect fit for Transmission & Distribution as well as industrial drives. An upgrade from older chip generations is feasible thanks to the standardized IHV B package of 190 x 140 mm.

Both modules can realize 50% higher output power at the same size, which in turn means cost-reduction for the system designer. For example the FZ1800R45HL4 is the first module to enable 1.4 GW HVDC Plants at 320 kV without paralleling. FZ1800R45HL4_S7, in addition, can be driven by applying a gate voltage of 25 V instead of the usual 15 V.

Over 100k pieces of IHV B 4500 V with IGBT3 are the reliable workhorses enabling a stable green grid, now the new FZ1800R45HL4(_S7) will follow this heritage with even lower losses.
