Abstract: A wound multi-capacitor filter for suppressing R.F. interference signals on power lines is formed by winding into a roll a floating sheet electrode that is sandwiched between two dielectric layers, a pair of spaced equal area sheet electrodes and another electrode being in contact with the outer surfaces of the sandwiching dielectric layers. The pair of electrodes are connected to two power lines that deliver energy to a device such as a motor, while the other electrode is connected to a grounded terminal. This filter provides either a reduction in AC leakage or an improvement in noise attenuation or both compared to a conventional delta-connected filter.
