A buck“boost transformer is a autotransformer used to make small adjustments to the voltage applied to alternating current equipment. Buck“boost connections are used in several places such as un interruptible power supply (UPS) units for computers in the tanning bed industry. Operating electrical equipment at other than its designed voltage may result in poor performance, short operating life, or possibly overheating and damage.For large adjustments in voltage (more than 15% to 20%), usually a two-winding transformer is used with the required voltage ratio, for example 240VAC to 120VAC. These Transformers are more costly than buck“boost transformers since both windings must carry the full power delivered to the load
