4 Summary

When selecting the driver for the power transistor, it is important to ensure that proper gate drive voltage is provided to fully enhance the power switch and minimize power losses. The most popular choices for power transistors in HV systems are Si MOSFETs, SiC MOSFETs and IGBTs. Typically IGBTs and SiC MOSFETs require higher gate drive voltage than Si MOSFETs to fully enhance the device. While one TPSI3050 device can provide sufficient gate drive voltage for Si MOSFETs, two TPSI3050 devices can provide different gate drive voltage options to optimize power dissipation in IGBTs and SiC MOSFETs.
