Abstract
Impedance values of a common mode choke coil, an impedance element disposed anterior to the common mode choke coil and an impedance element disposed posterior to the common mode choke coil are determined in such a manner that a common mode current flowing into the common mode choke coil does not exceed a value of rated current. Excessive common mode current is prevented from flowing into the common mode choke coil, and saturation and damage of the common mode choke coil is prevented.
