FUNCTIONAL DESCRIPTION

IS200GDDDG1A is a Gate Driver and Dynamic Discharge Board manufactured and designed by General Electric as part of the EX2000 series used in excitation control systems. The interface separation between the IGBTs and the main processor firing circuits is provided by the Gate Driver and Dynamic Discharge board (GDDD). Both the gating circuits for the A and B leg active IGBTs and the GDDD board employ dynamic discharge circuit control. This board also offers the regulator's instrumentation. The LDCC processors receive the output dc voltage, dc-link voltage, shunt current mV input, and the heat sink thermistor input after being processed on the GDDD board for use by the regulators.

Fig 1: Typical Connection Diagram

IGBT gating for bridge output and Dynamic Discharge control is controlled by Gate Driver and Dynamic Discharge (GDDD). Additionally, it isolates and scales the shunt feedback, heat sink temperature feedback, dc output, and dc link voltage. This circuit is typically powered by the GDDD board, however, if control power is lost, it may also be powered by the dynamic discharge power source resistor RDS.

• The dynamic discharge circuitry on the GDDD board regulates the C leg of the 3-phase IGBT pack. In the case that control power is lost, a backup power source is supplied to the GDDD board using the RDS resistor for the discharge circuit.

• The control level of the dc link by the dynamic discharge circuit is set by jumper settings on the GDDD board.

• The dc link capacitors are connected to the IGBT bridge via the IAXS board, along with dynamic discharge control and gate control from the GDDD board. The IAXS board serves as a connection point for the control circuitry's sensing feedback and dc output voltage.
