Web7. Why do buck-boost transformers have 4 windings? To make them versatile! A four winding buck-boost transformer (2 primary and 2 secondary windings) can be connected eight different ways to provide a multitude of voltage and kVA outputs. A two winding (1 primary & 1 secondary) buck-boost transformer can be connected only one way. 8. WebIn simplest terms, a bucking transformer is a way of reducing line voltage. A transformer's secondary is used in opposite phase to the power line input, and the result is a reduction in line voltage. In cases like mine, where a few volts of reduction is all that's needed, they can be an invaluable tool.
