Re: Six Phase Power

Hi David

If you use a center tapped (CT) secondary transformer (X3) with HV 3ph applied to primaries, and tie all CT's together on secondaries, will easily make a 6ph output. 12 ph can be also done using delta wired primaries on one 3ph transformer bank and wye wired primaries (1.73V ratio on primaries) on other transformer bank Both banks center tapped connections are tied together will make 12 ph. 'n' phases can be created by appropriate tapping of a extended delta (with wye extension) taps to adjust relative phasing. See North's Transmitter Book (power supplies) at Jim Lux's site for more info...

I built a 6 ph high power linear power supply (0-22V @200A) for R&D using this method to allow +/-11V referenced to equipment ground (120-208Y input), so first method mentioned definitely works... ;^D
