Abstract:
An apparatus for eliminating noise in an AC power waveform, which is connected between an AC power supply and a power input of an AC electromagnetic device in order to eliminate noise in an AC power waveform, characterized in that:at least one of lines of individual phases (e.g., L and R) of said AC power supply is separated into a branch line a and a branch line b connected in parallel; each of said parallel-connected branch lines a and b forms a series circuit of a single PN junction element ta capable of producing a Peltier effect and Seebeck effect within the same element and a single diode d; said parallel-connected branch lines a and b are connected at an input-side node C or E and an output-side node D or F, forming a circulating current loop; an AC power input terminal (IN) is provided with an input connector, an attachment plug or an attachment plug with a power cord; and an AC power output terminal (OUT) is provided with an output connector, an outlet or an outlet with an extension cord.
