<P>PROBLEM TO BE SOLVED: To provide a voltage converter capable of reducing noise generated by a current which flows through the wiring. <P>SOLUTION: A power supply circuit 100 has a first wiring structure where a first current flows in the direction which generates a first magnetic field when a switch part SW11 is in a predetermined switch state and a second wiring structure where a second current flows in the direction which generates a second magnetic field which negates the first magnetic field when the switch part SW11 is in the predetermined switch state. Moreover, the first and second currents may be the currents of a harmonic component of the fundamental frequency of the current which flows in the voltage converter. <P>COPYRIGHT: (C)2013,JPO&INPIT |
