Abstract :
Increasing switching frequencies and faster switching transitions in switched mode applications extend the harmonic content of voltage and current, a magnetic component is stressed with far beyond its first resonance frequency. Several problems occur like oscillations due to parasitic reactive currents and radiation by leakage fields and they become a critical issue to a design. This contribution focuses on those effects and phenomena not being reported yet and shows solutions to the related problems.
