Yes, but based on simulations and research by Richie Burnett, you can't
really achieve a power factor of better than 0.93, because of the way the
current waveform is distorted from the load presented by the TC. Anyways, a
power factor of .9 or thereabouts is quite good really, especially since we
don't run coils for all that long.
