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. WebThe bucking transformer works by placing the secondary of a (relatively small) transformer in series with the mains, but wired out-of-phase so the voltage is 'bucked' or reduced by subtraction. Only the secondary …
