Abstract :
Estimation of the error in power switching loss measurement is presented. The analysis is based on the modeling of the current and voltage probes, including the cables. It is shown that the measured waveforms are not simply delayed by the probes, but overshoots and distortions are introduced by the probes, that may not be corrected easily, thus introduce errors. Accurate comparisons between simulation and measurement results are discussed when adequate probe models are used in simulation
