      3. There is no phase shift for zero sequence. Transformer tap magnitudes can be adjusted to control voltage, and transformer phase shifts can be adjusted to control active power flow. The effect of these "off-nominal" adjustments can be incorporated into a pi-equivalent circuit model for a transformer. Figure 5. Off-Nominal Transformer Circuit ...

      To get a graph like Fig. 3, I sometimes have to move one of the red leads in Fig. 2 to the opposite end of a transformer secondary. In Fig. 3, the period of each waveform is 16.7 msec, which corresponds to the 60 Hz frequency of the alternating current.

      It is also possible to have all three regulators using the same phase voltages and current for input control signals in which case the 3 regulators will always be changed by the same number of taps. Finally, there is also available and in use the so-called three-phase regulator (in contrast to three interconnected single phase regulators).

      The Current continues to the winding in phase U then goes through the phase V winding. From there current goes through the MOSFET in phase V on the low side. Then the timing from the microcontroller will make the current flow through the different phases at different times indicated in Figure3.
