We are looking for a solution to use a 3 phase network to supply a 1 phase load.
We are aware of the LeBlanc, Scott-T and Open-Delta arrangements. However they don't meet our requirements as the link below explains.
We are also aware that 12 leg 3 phase alternators can be reconfigured to 1 phase and ask why can't a similar concept be used in a transformer?
Basically we are looking for a transformer configuration (with no electronics) which will present a single phase load as balanced on a 3 phase network. The transformer may not be optimal in terms of efficiency or may need to be oversized.
