People working with emitter/source followers do not like it either and I cannot see the folks using inverters wanting to pay to put big resistive heaters across the grid to compensate. Adding power factor correction to switching power supplies was cheap compared adding "negative resistance" correction. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
