Abstract
The ringing oscillation in turn-off of diode may induce electromagnetic interference (EMI) noise especially in fast switching operation. This study compares static and dynamic characteristics of a Si PiN diode and three type SiC Schottky barrier diodes, which have comparable voltage and current ratings, and focuses on the influence of diode characteristics on conducted emission of the continuous current mode (CCM) DC-DC boost converter. The dynamic characteristics of diode current in turn-off operation are evaluated by Prony´s method. The spectrogram of conducted emission is measured to understand how the noise source could affect the conducted noise emission.
