摘要：PROBLEM TO BE SOLVED: To obtain a post-mounted or an externally mounted device where white noise contained in an AC waveform supplied from a commercial AC power supply, parasitic noise due to electromagnetic interference, or the like does not adversely affect electromagnetic equipment which receives the power. SOLUTION: A P-N junction element ta is applied to a power circuit, where the P-N junction element ta is effective when mounted to each signal and communication functional circuit, activates Peltier effect and Seebeck effect in the same element, and gives noise reduction effect. At least one out of the lines between an AC power input terminal IN and an output terminal OUT to high voltage equipment is set to parallel branch lines (a) and (b), and an externally mounted device is composed by connecting the series connection body between diodes da and db and P-N junction elements ta and tb to both branch circuits, thus facilitating the utilization by a general user.
