I am working with a motor controller that runs a 3 phase switched reluctance motor. I am in the process of replacing the freewheel diodes
for the power mosfets. The originals are ST microelectronics number BYW98 200 fast recovery diodes. These are rated at 200 volts. I would like to upgrade these with 400volt units but some I am running across are ultra fast recovery. Would using the ultra fast recovery units cause a problem if I were to use them?
The mosfets I will be using are Fairchild FQP17N40.
Thanks
