FUNCTIONAL DESCRIPTION:

IS200GDDDG1AAA is a Gate Driver and Dynamic Discharge Board manufactured and designed by General Electric as part of the EX2000 Series used in GE Excitation Control Systems. The IS200GDDD Gate Driver and Dynamic Discharge board provide the interface isolation between the IGBTs and the main processor firing circuits of the EX2000 PWM-based exciter. Dynamic discharge circuit control is implemented on the GDDD board as well as the gating circuits for the A-leg and B-leg active IGBTs. The board also provides the instrumentation of the EX2000 PWM. Output dc voltage, dc-link voltage, shunt current mv input, and the heat sink thermistor input are processed on the GDDD board and sent to the LDCC processors for use by the regulators.

Three jumpers, JP1–JP3, on the GDDD board are used to configure the following components:

• JP1: JP1 jumper configures the input level of the dc output voltage to the GDDD board inputs APL- 6 and BPL-5. It must agree with the value in EE.612 (VDCMAX).
• JP2: JP2 jumper configures the input level of the dc link voltage to the GDDD board inputs CPL-12 and CPL-2. It must agree with the value of EE. 612 (VDCMAX).
• JP3: JP3 jumper configures the input level of the dc dynamic discharge reference to the GDDD board on inputs CPL-12 and CPLCOM. It should correspond to the level in EE.612(VDCMAX) such that for EE.612 = 604, JP.3 = 500, and EE.612 = 360, JP.3 = 300.

TEST POINTS:

• TP1 Analog 0-5 V proportional to the PWM bridge output voltage.
• TP2 Analog 0-5 V proportional to the PWM bridge output current.
• TP3 Analog 0-5 V proportional to the PWM dc link voltage.
• TP4 DCOM common reference for GDDD board signals

FREQUENTLY ASKED QUESTIONS

What is a gate driver?

A gate driver is a device used to control the switching of power semiconductor devices such as MOSFETs or IGBTs. It ensures that the devices switch on and off efficiently and reliably by providing the necessary voltage and current levels to the gate of the semiconductor.

Why is a gate driver important?

Gate drivers are essential for power electronics applications as they enable precise control over the switching characteristics of semiconductor devices. Proper gate driving ensures efficient operation, minimizes power losses, and enhances overall system reliability.

When should I consider using a dynamic discharge board?

A dynamic discharge board is particularly beneficial in high-frequency switching applications or when minimizing switching losses is critical. It is often used in applications such as motor drives, power inverters, and renewable energy systems.
