Hello,
I have a 60Hz AC voltage comming from a transformer 120/220V that
powers some cooling fans, but it's got some spikes at the output, and
Im having problems with that. The spikes are burning the fans.
Here is the link of the wave form: http://br.geocities.com/suellemtosi/

What the main problem is at 2Khz, am I right?
I want to make a filter to attenuate those spikes, but I´ve never done
a filter for voltages above 12V. I know just how to use op-amps, but
for 220V Its got to be a passive filter.
Does anybody have an idea of what type of filter would be more
appropriate? Low pass, tuned filters....
I have JUST some 3,9mH inductors to make it, the other components can
be anything to match the configuration.
Anything will be helpful!!!
Thanks a lot!
