Hardware Tips and Specifications

The required operation of the IXTD board is provided through the circuitry

of the connected power supply/interface board (IMCP).

When the IMCP and the IXTD board are connected, they are connected via a four-pin connector.

When the board is installed, it will be externally mounted and must

be sized to meet the worst-case switching requirements of dynamically braked IGBTs.

The purpose of the snubber board is to be used to limit voltage transients

​at both ends of the IGBT and at all known operating conditions of the driver.

Another function of the DS200ITXDG1ABA board is to regulate the output

of the IGBT gate driver board to match the electrical characteristics of the AT frame driver.

AT frame drivers are available in variable and constant torque applications.

The drive output current rating for variable torque applications is 500 ARMS.

The DS200ITXDG1ABA board has three connector types: bus I/O connectors,

input connectors for DBPL, and board pin connectors.

All of these connector types have different pin numbers, nomenclature,

and descriptions, which are explained in depth and in detail in the 

DS200ITXDG1ABA instruction manual included above for your convenience.

Bus I/O connectors and pin I/O connectors are also oriented. 

Two examples of pins associated with the stab I/O connectors are the

E-6 and E-9 connectors, both of which are output connectors.

The E-6 connector is the DB IGBT gate signal and the E-9 connector is the connection for the external buffer resistor.
