Just curious if anyone has heard if pfc has been applied to small motor drives (or even computers). I would imagine the european regulators will be pushing pfc as they love to impose rules. So down the road USA manufacturers will be forced to provide pfc.
A possible benifit would be a manufacturer could potentially produce one particular hp drive and use different pfc front end units.
example: produce a 1hp 230v 3 phase drive which would be the standard. If customer wants single phase operation sell him a pfc. If a customer wants to run 230v motor off of 120vac sell him a pfc. Maybe same pfc could be used for both applications - If not we're back to producing three units, a drive and two pfc.
