Buck-Boost Transformer
Buck-Boost Transformer Details
A buck-boost transformer works by taking input voltage from the primary side of the transformer and stepping it up or down – depending on the preferred configuration. Rectified voltage is then provided on the secondary side (output), where it can be used by a connected device or machine. If voltage is single phase, a single buck-boost transformer is applied. For three-phase voltage rectification, two or three units are utilized.
This type of transformer is very economical for businesses. Its small form factor enables installation around congested machine layouts, where space is severely lacking. The units are energy-efficient and less costly, compared to standard transformers.
Where are They Used?
Buck-boost transformers can be found in a myriad of fast-moving sectors, work sites and systems:
- Industrial lighting systems
- Electrical systems that experience sagging voltage
- Systems requiring low-voltage isolation (12V DC – 48V DC)
- Lengthy/extended electrical connections
- HVAC systems
- Power distribution
A common buck-boost configuration includes stepping up 208V to 230V or 240V (or stepping down 230V or 240V to 208V), as well as stepping up 240V to 277V (or stepping down 277V to 240V). In the mentioned examples, the units guarantee compatibility with mainstream voltages, such as 240V or 120V.
