The IS200DAMCG1ACB is an essential component that controls the high-power switching devices in the drive.

  • Gate Drive Amplification: Its primary role is to serve as the interface and amplifier between the low-level logic signals coming from the central drive control board (like the BPIA board) and the high-power Insulated Gate Bipolar Transistor (IGBT) modules.
  • Precision Switching: It converts the low-power logic into the necessary high-current, precise voltage pulses required to switch the IGBTs quickly and reliably. This precision is critical for efficient motor/generator control and for preventing catastrophic faults like “shoot-through” (where both the upper and lower switches of a phase leg conduct simultaneously).
  • Frame Rating: The board is specifically designed for the 250 Frame rating of the Innovation Series Drive.3 This means it is optimized to work with IGBT modules rated for that power level, such as the Powerrex CM400HA-28H.4
  • Configuration: A complete three-phase drive system typically requires three of these boards, with one board assigned to control the IGBTs for each phase leg.
