Influence of parasitic effects on passive cancellation of common mode noise in a boost converter

摘要

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, to the authors' knowledge, a thorough investigation of parasitic effects has not been published yet. It turns out that the parasitic effects are crucial for this passive cancellation method. Therefore it is of great interest to investigate this influence. In combination with a finite differential mode (dm) filter capacitor C
