Buck-Boost Transformers Selection and Application Guide

This document provides a comprehensive guide on selecting and using buck-boost transformers to correct off-standard voltages (5-20% too high or low) for electrical equipment, including AC motors, resistive heating, and lighting. It covers features, advantages (efficiency, size, cost) and disadvantages (no isolation, no neutral creation), along with selection charts, connection diagrams, and full-load current tables for single-phase applications.
