         [0017]    When currents respectively flow through two neighboring inductors, the inductance of the inductors not only includes self inductance generated from currents flowing through each inductor&#39;s coil, but also includes mutual inductance. Therein, when one of the two neighboring inductors experiences electric potential change upon its coil, then the other inductor&#39;s coil may also experience changes, and this is the aforementioned mutual inductance. Because the coil winding structure according to the present invention, when the current flows through the two coil windings of the reformed inductor  1 , self inductance and mutual inductance is generated simultaneously, so that the require number of coil winding loop from a single inductor is less than the number of coil winding loop from using two inductors respectively placed on a hot line and a neutral line, and yet the same amount of inductance is still achieved. Also, because the number of coil winding loop is reduced, therefore the resistance from the wire is reduced and power loss is lessened.
