Dynex IGBT 3.3kV to 6.5kV modules are suitable for a number of power applications and offer significant features; 10µs short circuit withstand, high thermal cycling capability and high current density
Dynex offers Dual IGBT and Half Bridge IGBT modules for 3300V to 6500V products which are capable to facilitate less costly implementations of I Type and T Type converters which offer increased efficiencies vs typical 2 level converters.
Most importantly among Dynex’s IGBTs, is the ability to choose our Low Switching Range (F), Low Conduction Range (L) or Standard Range (S).
The STATCOM is ubiquitous in grid applications; below a 6 level converter in which each level can utilise Dynex’s optimised IGBTs.
The IGBTs that operate from 0 to ±3300V conduct for the majority of their cycle and switch for a minority of their active cycle; this portion of the application lends itself to the Low VCE – Low Conduction Loss Range optimised DIM1200ASM45-TL000.
In contrast the IGBTs that conduct from ±6600V to ±10000V switch for the entirety of their active cycle; therefore, the Low ESW optimised DIM1200ASM45-TF000 is considered the preferred selection.
Conversely, the IGBTs that operate from ±3300V to ±6600V have switching vs conduction cycles that are approximately equal; this portion of the converter would be better served by the standard variant DIM1200ASM45-TS000.

Dynex’s Bipolar products offer a range of devices that suit Power and Grid Applications:
Dynex’s Bipolar products are highly reliable and suitable for power grid, HVDC, solar and wind farm applications. The devices are offered in 1400V to 8500V and encompass double side cooling and high surge capability. The devices are designed in a variety of package outlines to suit power application requirements.
The ACR Range of Asymmetric Bypass Thyristors can be paired with Dynex IGBTs to proect the IGBTs from DC faults with blocking voltages of 3300V and 4500V.
Dynex DCR Range of Phase Control Thyristors can be optimised for switching or conducting losses in order to suit crowbar, rectification or line reactor applications.
