Dear All,

I need to replace an output filter that is no longer available on themarket and is quite old. I have its topology but I am not sure whether it is a dv/dt filter (motor choke) or a sinusoidal filter. Please see attached image.
The filter goes between the power drive and the motor. Rated power is 20 kW.

Any ideas?
Thanks for your comments.
Rod.
