The phase-to-neutral voltage of two of the phases will be half of the phase-to-phase voltage.

The second transformer is connected to a center-tap of the first transformer, and is wound for 86.6% of the phase-to-phase voltage on the three-phase system.

This has two bushings on top which are connected to two of the three primary wires, so the voltage across the primary winding is the phase-to-phase voltage.

Phases with higher relative loading will experience reduced voltage, and phases with lower relative loading will experience elevated voltage, up to the phase-to-phase voltage.

The DC output voltage from this arrangement is 73% higher than that obtained from the 3-pulse and single phase designs, because the 6-pulse rectifier extracts the maximum phase-to-phase voltage.

The neutral point in a three phase system exists at the mathematical center of an equilateral triangle formed by the three phase points, and the phase-to-phase voltage is accordingly 3 times the phase-to-neutral voltage.
