SECTION 2
Why Use Buck-Boost Transformers?
follows:
Buck-Boost Application
above or below normal. When a buck-boost transformer is connected as an autotransformer, only a portion of the
load kVA is actually transformed. The majority of the load kVA is passed directly through to the source. For this
reason a buck-boost transformer may be used to supply a much larger load kVA than is indicated on the name-
plate.
regulated with a Line Voltage Conditioner. Refer to ‘Section 6’ for details.

The advantages of using a buck-boost transformer over an equivalent standard isolation transformer are as
Advantages
1) Used in a variety of applications
2) Inexpensive
3) Smaller and lighter
4) More efficient
5) 5-10 times increase in kVA
Disadvantages
1) No circuit isolation
2) Cannot create a neutral
3) KVA and voltages do not match what’s
Buck-boost transformers offer an economical solution to the adjustment of line voltages that are slightly
Buck-boost transformers can be used to adjust stable voltages only. Fluctuating line voltages should be
