I doubt that. But since I am at luxury of having Matlab at my fingertips most of the time, here's a comparison:Re: 4 phases v. 3 phases. I think the harmonics would require more filtering than with a 3phase. The ripple is smoother but the neutral current would be higher than 3ph. The odd harmonics [especially the non-triple ones, 5th, 7th, etc] would cause a little more noise. But I am reaching back a few decades on that, so I'm likely wrong or conflating something
