Re: Three phase transformer
That diode configuration (of 6 diodes) is typically referred to as a full bridge.
Did you energise just a side leg winding when you measured the 1/3, 2/3 ratios?
If you energise two adjacent legs equally and in phase addition, then I'd expect the third limb to effectively have no flux through it. With 230V on two windings in phase addition, the flux level in each energised limb is about 15% more than rated.
Are you saying you need a 150Vrms, 25A supply that will be in phase with a 230V generator supply, to ultimately provide a 380Vrms single phase supply?
