Description
DS200IIBDG1AEA Product Overview
The DS200IIBDG1AEA is an IGBT driver/interface “personality” board used inside GE Mark V Speedtronic and EX2000I medium-voltage AC-drive cubicles. It occupies a single VME slot and delivers gate-drive pulses, fault feedback, and medium-voltage isolation for the IGBT power bridge—allowing the controller to switch 480–4160 V IGBT modules without exposing the low-voltage backplane to high dv/dt.

In the drive hierarchy the card sits at the “power-switch interface” layer:
-
It receives 24 V logic-level gate commands from the triple-redundant CPU,
-
amplifies them to ±15 V gate-drive pulses,
-
returns desaturation, over-temperature, and under-voltage faults over opto-isolated lines, and
-
houses on-board snubber capacitors that clamp dv/dt spikes during fast IGBT turn-off.
Because the board is passive (no microprocessor) and carries conformal coating, it qualifies as a “simple device” for safety-related turbine-compressor drives, avoiding additional software V&V.

Typical Applications
In combined-cycle power plants the DS200IIBDG1AEA is installed in Mark V drive cubicles that feed the gas-turbine compressor motor. It amplifies gate pulses for 1700 V IGBTs while reporting desaturation faults to the CPU, ensuring the compressor stays on-line during rapid acceleration .

In pipeline booster stations the same card is used in 4.16 kV VFDs that drive centrifugal compressors; the on-board snubber network keeps turn-off overshoot below 5 % during regenerative braking .
Because the board is certified for marine environments, it is also used on off-shore platforms for well-boost compressors where a fan-less, Zone-2, simple-device gate driver is mandatory .
