About the IS205IGDHG1A
The IS205IGDHG1A functions as an IGBT or Insulated Gate Bipolar Transistor Gate Driver Board. This is a sub-assembly for the IS200PICH board. It provides the majority of the circuitry needed to interface an IGBT module to the control logic. Each PICH board uses eight IGDH sub-assemblies and their associated isolated power supplies. These connect to the primary board via a 57-pin connector that is used to solder the board into place. The IS205IGDHG1A:
- accepts and decodes gate ON/OFF and soft shutdown logic level commands at the command input
- outputs the typically-appropriate IGBT gate signals
- can create a fault status that will cause the status feedback to turn off and a soft shutdown fault to inhibit the gate drive
This typically happens if the +/-15 V monitor is less than +13.5 to +12.9 V or when the -15 V is greater than -13.5 to -12.9 V. The board also returns a desaturation fault by taking the IGDH FOUT (fault status output) low. Interestingly enough, this IS205IGDHG1A printed circuit board or PCB for short is actually not the originally-produced device of its specific Mark VI Series functional role, as that would have to be considered the IS205IGDHG1 parent printed circuit board not making use of this IS205IGDHG1A product's typical A-rated functional product revision.
IS205IGDHG1A Hardware and Part Number
The IS205IGDHG1A is populated by forty-six resistors, thirty-four capacitors, twenty-eight diodes, and ten integrated circuits. Codes like 6BA02, 6BB02, 94V-0, 3802, and TTM-4 are marked on the board surface.
The IS205IGDHG1A functional product number itself can be heralded as an alternative primary source of IS205IGDHG1A board hardware component and component specification detail; as it codes for particular informational nuggets in a series of General Electric-formulated functional naming segments. For example, this particular IS205IGDHG1A functional product number actually begins with a dual-functioning naming component in the initial IS205 series tag indirectly responsible for naming this IS205IGDHG1A device's domestic manufacture location on top of its special 205 assembly version. Some of the other relevant hardware specifications in this product number include this IS205IGDHG1A PCB's:
- IGDH functional product acronym
- Normal PCB coating style
- Group one Mark VI Series product grouping
- A-rated functional product revision
