<P>PROBLEM TO BE SOLVED: To provide a method of easily and inexpensively reducing a common mode current flowing between the earth and an internal ground of an electrical circuit to which an AC voltage is supplied by an electrical network. <P>SOLUTION: In the method, a voltage is applied by an electrical network 2 between an internal ground 13 of an electrical circuit 4 and the earth, and an additional voltage having a phase opposite to that of the voltage applied by the electrical network 2 between the internal ground 13 of the electrical circuit 4 and the earth is applied between the internal ground 13 of the electrical circuit 4 and the earth using an electronic component interposed between the internal ground 13 of the electrical circuit 4 and the earth, so as to reduce a common mode current i. <P>COPYRIGHT: (C)2013,JPO&INPIT |
