Flyback transformer including a plated metal coil and having reduced leakage flux

摘要

A flyback transformer includes at least one primary coil and at least one secondary coil formed thereon. Each primary and secondary coil may be a metal plating coil with an insulating bobbin and a conductor formed thereon. Secondary coils may be formed of pairs of metal plating coils connected in series. One to three primary coils may have secondary coils sandwiched therebetween. The transformer may also have a resonance capacitor integrally formed therein, and may have respective rectifying diodes connected between the secondary coils.
