Which limitation affects the cascading of multiple DC-DC power converter systems operating at high frequencies?

💡 Explanation

When DC-DC converters are cascaded at high frequencies, increased EMI occurs because each converter stage generates its own switching noise, which cumulatively worsens. Therefore EMI results, rather than efficiency reduction, synchronization or voltage stress, all of which are secondary effects which would affect a different area.
