ABSTRACT:
A device and method for reducing low frequency electromagnetic fields in an electric blanket includes an input, a rectifier filter, and a pair of closely spaced resistance wires. The input is connected to a 60 Hz AC power source to supply power to the electric blanket. The rectifier filter rectifies the input signal and filters out any high order components. The rectifier filter provides a filtered DC signal to apply across the paired resistance wires. In one embodiment, the device and method includes an output for connecting to a conventional electric blanket where the rectifier filter provides a filtered DC signal to the output.
