The IS200GDDD series of printed circuit boards are described as being Gate Driver and Dynamic Discharge, which, according to the Digital Exciter manual, “provides the interference isolation between the IGBTs and the main processor firing circuits. Dynamic discharge circuit control on the GDDD board as well as the gating circuits for the A leg and the B leg active IGBTs.” The IS200GDDD printed circuit boards’ main goal is to properly operate the gating control systems of the IGBTs for both the Dynamic Discharge control and for bridge output. Additionally, the IS200GDDD printed circuit board also is able to isolate and scale the DC output, the DC link voltage, the heat sink temperature feedbacks, and the shunt feedback.
The IS200GDDD printed circuit boards are also used as the main routing location for power circuitry. The C-leg of the three-phase IGBT pack is controlled by the dynamic discharge circuitry, which is located on the IS200GDDD printed circuit boards. Also, the IS200GDDD boards are home to an alternate power source, which is used for the discharge circuit and is given to the rest of the unit through the RDS resistor. This alternate power source, however, is only used when control power is no longer available. Also located on the IS200GDDD printed circuit board are the jumper settings, which has the primary goal of setting the control level of the dc link by the dynamic discharge circuit.
