IS200DAMBG1A

The IS200DAMBG1A is a Gate Driver Board manufactured and designed by General Electric as part of the Mark VI Series, used in GE Drive Control Systems. A gate driver board is an electronic circuit used to control the switching of power semiconductor devices, such as MOSFETs, IGBTs, or SiC devices. It delivers a low voltage signal to the gate of the power device, turning it on or off, and is designed to drive the gate capacitance quickly and efficiently. Gate driver boards are widely applied in power electronics applications such as motor drives, inverters, and power supplies. They typically provide high-current pulses with fast rise and fall times to minimize switching losses and enhance efficiency.

Features

• It provides a convenient interface between a control rack interface and an IGBT power-switching device.
• The DAMA boards are 620 frame boards equipped with a CM1000HA-28H Powerrex IGBT and are designed with three boards per drive—one for each phase leg. The device includes only one IGBT for the upper phase leg and one IGBT for the lower phase leg.
• The DAM_ boards are directly connected to the IGBT collector terminals, gates, and terminals, as well as the BPIA Bridge Personality Interface board located in the control rack. Additionally, there are no test points, fuses, or configurable items on the board.
• Pin 1 is named GLIN, which functions as the lower gate signal. Pin 2 is designated as the lower common signal (LCOM), which corresponds to the emitter. Pins 3, 4, 8, and 9 are labeled NC (Not Connected).
• Pin 5 is designated as the lower collector signal and is labeled CL. Pin 6 is designated as the upper common signal (UCOM) (emitter). Pin 7 is labeled GUIN and functions as the upper gate signal, while Pin 12 is labeled CU and serves as the upper collector signal.
• Gate driver boards may include features such as overcurrent protection, overvoltage protection, undervoltage lockout, and fault detection to ensure the safe and reliable operation of the power device. They may also be designed to operate at high temperatures and in harsh environments, such as those found in automotive or industrial applications.
