Hello,
This question is about the dimensioning of the fuse to be placed in my application of inverter. I have calculated the current rating considering various derating factors.
Now, I want to dimension the fuse as per its I2t rating. I amaware that Fuse I2t should be less than the Semiconductor I2t etc. I am looking for some document which has some steps to calculate and co-ordinate I2t of fuse with that of the application.
I will be grateful for your help.
Regards
Aalok
Aalok,
Pick up any book that describes fuse coordination at load ends - the principles are more or less identical (other than motor starting currents).

Download EasyPower demo and model your inverter. Use Power protector module and chose fuse ( you have many producers in database) and create TTC plot to see protection cooordination of your inverter supplied with chosen fuse
Also consider coordination of your inverter both upstream and downstream as required by code
