Device and method for adjusting effect of direct-current filter capacitor

The invention discloses a direct-current filter capacitor effect adjusting device and method, and relates to the technical field of electronic devices, and the device comprises a current regulator and a double-winding inductor. The double-winding inductor comprises an iron core, a working winding and a control winding, and the working winding and the control winding are both arranged on the iron core; the control winding is connected in series with the current regulator; the working winding and the filter capacitor are connected in series to obtain a capacitance-inductance branch; the capacitance-inductance branch and the load are connected in parallel to two ends of the direct-current power supply; and the current regulator is arranged between the direct current power supply and the load, and is used for sampling the current of a branch where the load is located, and adjusting the direct current in the control winding according to the sampled branch current, so as to change the inductance value of the workin
