  • Electrical filter for attenuating oscillations in AC mains
    Patent number: 5805032
    Abstract: In order to avoid filter excitations of subharmonics or intermediate harmonics, that is to say of oscillations in the frequency range between integral harmonics of the mains frequency (f.sub.N), in the case of an attenuation resistor (R1, R3, R3') in parallel with a series resonant circuit comprising a filter inductor (L1, L3) in series with a filter capacitor (C1, C31, C31'), the resistance is dimensioned in such a way that a current gain of the filter (F1-F3) at its frequency pole points with an AC mains (1) is not greater than 6-fold. Double low-pass filters (F1, F2) and high-pass filters (F3) with attenuation resistors (R1, R3, R3') are particularly suitable as filters (F1, F3).
