6 FAQs about [Igbt cost ratio in energy storage inverter]
Should a solar inverter be rated to the IGBT?
For a typical operation of a solar inverter with cosφ=0.8, the losses in the FWD are much smaller and hence a smaller rated device could be chosen. However, if a storage application is considered with a power factor of cosφ=-1, the losses in the FWD are maximal and thus the device should be equally rated to the IGBT.
