Thermal Derating vs Switching Frequency for 600kW Inverter

Our team needs 300+kW inverter to drive high speed motor requiring 3kHz output electrical frequency. For reliability and growth purpose we plan to use derated power inverter. We are not sure if the CRD300DA12E-XM3 300kW inverter would be enough in that case. The CRD600DA12E-XM3 600kW inverter seems like a good choice operating in parallel to get comfortably above 300kW. Can you provide us some thermal data (inverter power derating and/or virtual junction temperature) as a function of the switching frequency?

Thank you!
