Principle of switch loss of probe module

Hi Emma, to be clear, only the top plot (impulse signal type) is correct and relevant for the switching losses. But as for your question, the duration/width of the other two waveforms is simply based on the step sizes that are taken by the continuous/variable-step solver at any given time. PLECS is not actually integrating these waveforms though- the scope simply “connects the dots” artificially with those signal type options.
