PURPOSE:To secure the modulation for the inflow current of any waveform by selecting the capacity C and inductive reactor L of the matching circuit so as to secure the resonance with the modulated signal frequency produced at the modulator, thus ensuring an extremely steady operation. CONSTITUTION:Matching circuit MC is inserted between modulator MOD and the signal injection point between main transformer MT and several distribution lines. And circuit MC consists of reactor L and capacitor C. Thus commercial power voltage EO generated at transformer MT is applied to imedance R including the load on the several distribution lines via leak inductance LO. And inductive reactor L and capacity C of the matching circuit are selected so as to secure the resonance with the modulated signal frequency produced at modulator MOD. As a result, the inflow current of any waveform can be modulated, thus ensuring an extremely steady operation. |
