... NOTES: BG2D – Solderless Connection Gate Drive Prototype Board Description: The BG2D is a two channel gate drive circuit for that the dual NX series modules’ pins plug into directly. The BG2D utilizes Powerex hybrid gate drivers and converters to provide efficient switching of modules rated up to 450A ...

... Thermistor Connection: The case temperature of the NX series device can be monitored by reading the resistance value of the built in NTC Thermistor. This is accessed on the BG2D board at TH connector pins 1 and 2. The relationship between the resistance and the temperature measurement is given by the B constant as shown in equation 1. Solving for temperature of any given point Tx, with a reference temperature of 25°C we can come up with equation 2 ...

... EQ. (lnR EQ.2: T Printed Circuit Layout: Figure 5 shows the layout of the BG2D two channel gate driver board. The compact 3” x 2.2” circuit board with only 28 components clearly demonstrates the advantage of using hybrid gate drivers and converters. One important feature is the use of three ground plane islands for the regions of the PCB having high voltage differences ...
