Is it good or even used practice to filter out common-mode EMI in 3-phase industrial inverter (IGBT) phase outputs using phase-to-earth Y-capacitors? High du/dt might limit the lifetime of such capacitor, can ceramic y-capacitors handle this if film capacitors are in problems? 1000-3000V/us was mentioned in film capacitor's datasheet of for example TDK B81123. Any reason to use the caps in the phase outputs from the IGBT protection point of view (suppress voltage spikes or ESD)?
Wasn't able to find any literature related to the issue. Also DC-link could be tied to earth using Y-caps, not much of that either.
