<P>PROBLEM TO BE SOLVED: To provide a small noise filter which blocks a noise current from flowing outside. <P>SOLUTION: An input side noise filter of the noise filter used for a motor driving device is integrated with an output side noise filter for a smaller size. The configuration of common mode LC type allows reduction in high frequency noise and common mode current. A resistor is connected parallel to a common mode choke coil on the output side, preventing resonance of a filter current. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
