If you have something better, I'm sure the industry would accept it...but, you should approach the equipment mfg's with the idea. “On Demand” defrost has already been invented…thermisters sense a difference in temperatures between the outdoor coil and ambient…at some delta T, the system initiates a defrost cycle.

Maybe you could hook up an oscilloscope and show the phase angle created by the incorporation of a start capacitor into a psc motor. Either way, keep up the good work Thanks for the demonstration.
