Abstract :
Passive cancellation of common mode (cm) noise is a very promising alternative to a conventional cm filter. The basic idea has already been described in literature. However, a thorough theoretical investigation regarding the flyback that shows that perfect compensation should be possible has not been published yet. The given investigation provides a deeper insight into passive compensation and balancing in order to reduce cm noise in the flyback. Applying this knowledge to a hardware set-up reveals that very high cm attenuation is possible at lower frequencies.
