Stackable isolated voltage optimization module

A system, comprising:

• a plurality of stackable isolated voltage optimization modules (SIVOM) comprising a first SIVOM coupled to a first phase of a three-phase power system, a second SIVOM coupled to a second phase of the three-phase power system, and a third SIVOM coupled to a third phase of the three-phase power system, where each of the first, second and third SIVOMs comprises:
• a transformer comprising a primary winding supplied by the first, second or third phase coupled to that SIVOM and a secondary winding;
• and
• a switching circuit configured to boost or buck a voltage or change a phase angle of the phase coupled to that SIVOM by energizing the secondary winding of the transformer with a voltage provided from the three-phase power system, wherein:
• energizing the secondary winding of the first SIVOM with a voltage from the first phase and a neutral of the three-phase power system boosts or bucks the voltage of the first phase without affecting phase angle of the first phase;
• energizing the secondary winding of the second SIVOM with a voltage from the second phase and the neutral of the three-phase power system boosts or bucks the voltage of the second phase without affecting phase angle of the second phase;
• and
• energizing the secondary winding of the third SIVOM with a voltage from the third phase and the neutral of the three-phase power system boosts or bucks the voltage of the third phase without affecting phase angle of the third phase.
