<P>PROBLEM TO BE SOLVED: To obtain a small noise filter and an inverter unit with a built-in noise filter. <P>SOLUTION: A common mode inductance for current change suppression, consisting of a core and a coil is divided into three of L1-L3, and a capacitor C<SB>Xi</SB>on source side is connected in between the common mode inductance L1 on power source side and the central common mode inductance L2; a capacitor C<SB>XO</SB>on load side is connected in between the central common mode inductance L2 and the common mode inductance L3 on load side; and a capacitor C<SB>y</SB>on earth side is connected in between the neutral point of the capacitor C<SB>XO</SB>on load side and the ground side. <P>COPYRIGHT: (C)2008,JPO&INPIT |
