Buck Boost Transformer belongs to the category of transformers and its prime function is to make an alteration in the volume of voltage which is received via different current appliances and devices depending on their requirement. We can find the use of UPS technology, widely in the computer industry. This particular technology is used for tanning beds which are again based on the technology of buck booster transformer. Buck-boost transformers can also be used for powering any low voltage circuits. By low voltage circuit we mean control, lighting circuits, or also for those applications which needs 12, 16, 24, 32 or even 48 volts, which remains consistent with design as secondary.
