Difference between Buck-Boost Transformer and Standard Isolation Transformer
Buck-Boost Transformer
A buck-boost transformer is a type of autotransformer that adjusts voltage by ±5% to ±20% of the supply voltage. It fails to provide electrical isolation across the input and output.
Standard Isolation Transformer
A conventional isolation transformer contains separate primary & secondary windings to provide galvanic isolation between the input and output. It is mostly used for safety, noise reduction & grounding control rather than for voltage rectification.

Buck-Boost Transformer vs. Standard Isolation Transformer
| Feature | Buck-Boost Transformer | Isolation Transformer |
|---|---|---|
| Voltage Change Range | 5%-20% | Any range |
| Transformer Size | Small (voltage change only) | Large (full load) |
| Cost | Economical | Expensive |
| Efficiency | High (minimal losses) | Good |
| Primary Use | Voltage correction | Complete isolation |
