Abstract

PURPOSE:To absorb and eliminate effectively unnecessary ringing generated in a fly-back transformer, by connecting a parallel circuit consisting of a resistance and an inductance in series to the primary coil. CONSTITUTION:A parallel circuit 15 consisting of a resistance 13 and an inductance 14 is connected in series to a primary coil 2 of a fly-back transformer 1. The ringing current of the pirmary coil 2 caused by unnecessary ringing vibration of a higher frequency generated in a secondary coil 3 of the fly-back transformer 1 is absorbed by the parallel circuit 15. That is, the ringing current has energy consumed by the resistance 13 when passing through the parallel circuit 15.
