<P>PROBLEM TO BE SOLVED: To provide a power converter which incorporates a small electromagnetic noise countermeasure filter in a case. <P>SOLUTION: A normal mode coil 27 that uses a ferrite core is mounted on a positive electrode side output DC wiring 26 of a forward converter wired on a main circuit board 25 in the power converter. Further, a common mode coil 29 is mounted on a power source input wiring 28, and an interphase capacitor 30 is mounted between phases of the power source input wiring 28, and a ground capacitor 33 is mounted on a negative electrode side DC wiring 31 and a ground wiring 32. <P>COPYRIGHT: (C)2011,JPO&INPIT |
