IS200GDDDG1A is a Gate Driver and Dynamic Discharge Board manufactured and designed by GE. The interface isolation between the IGBTs and the main processor firing circuits is provided by the Gate Driver and Dynamic Discharge board (GDDD). The GDDD board, as well as the gating circuits for the A and B leg active IGBTs, use dynamic discharge circuit control. This board also provides the regulator's instrumentation. The GDDD board processes the output dc voltage, dc link voltage, shunt current mV input, and heat sink thermistor input before sending them to the LDCC processors for use by the regulators.
JP1 - JP3 jumpers on the GDDD board configure the following items:

What are test points, and why are they important?
Test points are specific locations within a system where technicians can access signals or measurements for diagnostic and monitoring purposes. They are crucial for troubleshooting, performance analysis, and maintenance tasks, providing valuable insights into the system operation.
How many test points are available within the assembly, and what do they monitor?
There are eight test points available within the assembly, each serving a unique monitoring function. These test points include analog signals proportional to PWM output voltage and current, DC link voltage, as well as specific signals related to dynamic discharge operations and PWM bridge DC output voltage.
How can technicians use analog TP1 and TP2 to assess the performance of the PWM bridge?
Analog TP1 provides a voltage signal proportional to the PWM output voltage, while Analog TP2 offers a signal proportional to the output current of the PWM bridge. Technicians can use these test points to monitor and analyze the voltage and current levels, aiding in performance optimization and fault detection of the PWM bridge.
How do TP7 and TP8 provide access to the PWM bridge DC output voltage?
TP7 and TP8, when combined, offer access to the PWM bridge DC output voltage. Technicians can use these test points to monitor the voltage output accurately, enabling comprehensive analysis and troubleshooting of voltage-related issues within the system.
Why are monitoring dynamic discharge commands and feedback values important?
Monitoring dynamic discharge command and feedback values (TP5 and TP6) allows technicians to assess the effectiveness of dynamic discharge operations. By comparing these values, operators can ensure proper control over discharge processes, enhancing system performance and safety.
