Bucking transformer using heater windings

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. WebJun 9, 2013 · But to avoid the possible saturation issues referred to (when using the boost configuration), put the buck or boost winding from the additional transformer in series with the secondary of the main HT power transformer. That way the HT transformer is known to be running within its design parameters.
