Can Buck-Boost transformers be used on 3 phase systems?

Interconnecting two or three single-phase units will readily accommodate three phase systems. The number of units to be used in a 3-phase installation depends on the number of wires in the supply line. If the 3-phase supply is 4-wire Wye, then three Buck-Boost transformers are required. If the 3-phase supply is 3-wire Wye (neutral not available), two Buck-Boost transformers are needed.
