I am working to design a static AC switch using an IGBT module. The idea is that the switch will protect an inductive load from an adverse voltage condition (such as excessive under or over voltage) and disconnect the load from the mains. For now, it will need to switch single-phase 120VAC, and the load will be 1kW or smaller.
The IGBT module I have selected is an Infineon FF300R12KT3_E module (https://www.infineon.com/cms/en/product/power/igbt/igbt-modules/ff300r12kt3_e/), which features dual common-emitter IGBTs. My schematic shows a standard optocoupler, but I am considering using an Infineon 1EDC60H12AHXUMA1 IGBT gate driver or similar (https://www.infineon.com/cms/en/product/power/gate-driver-ics/1edc60h12ah/). This will be powered from an isolated 20VDC power supply, and controlled via microcontroller. I have the IGBT modules but not the gate driver yet.
Does this design seem robust enough for my needs? The circuit is based off an older design design by International Rectifier (Now Infineon). I am not sure the resistor between the gates and emitter is necessary. Actually, I'm wondering if anything else could be done that might protect the gate regions against turn off oscillations. Any feedback would be much appreciated.
