Passive filter circuits used in the extraction from the harmonic power grids, passive filter and the original three-winding transformer coil-series, the transformer coil through the edge of a fundamental degaussing circuit into a fundamental reactive current fundamental degaussing, Another vice-coil used to extract harmonic voltage, as the harmonic voltage three-phase full-wave rectification and filter after the reactor and the DC motor armature winding associates and eventually achieve harmonic drag.

The electric circuit use passive filter withdraws the overtone from the electrical network, the passive filter with three winding transformer's primary side coil series, this transformer's side coil pours into the fundamental wave idle current through the fundamental wave degaussing electric circuit to carry on the fundamental wave degaussing, another side coil uses in withdrawing the harmonic voltage, this harmonic voltage after three-phase full-wave rectification unites
