Selection of Buck Boost Transformers for Motor Loads
Applies to Buck and Boost Transformers by SquareD/Schneider Electric
Motor Loads can have high inrush or Locked Rotor Current when starting
Buck Boost units can be sized based on the full load current and voltage differential. Since the impedance presented to the circuit by the Autotransformer connection is low, a locked rotor current condition will not cause a large IZ voltage drop across the Transformer(s).
