Frequently Asked Questions
Q: Does this driver support paralleling of different module part numbers?
A: No. For reliable operation and proper current sharing, it is essential to use identical power modules (same part number and batch if possible) when paralleling.
Q: What is the purpose of the +20V/-5V gate voltage?
A: This asymmetric gate voltage is optimal for SiC MOSFETs. The +20V ensures the device is fully turned on with minimum Rds(on), while the negative -5V provides a strong buffer against parasitic turn-on induced by high dv/dt, enhancing system reliability.
Q: Is the fiber optic receiver included?
A: The driver has the onboard receiver. The fiber optic cables and transmitter on the controller side are typically sourced separately. We can recommend compatible components.
