Overview
Compare positive and negative line-cycle conduction, power factor, low-order harmonics, charging ripple and semiconductor stress. State filter, load and sampling assumptions so waveforms can be reproduced.
Why validation matters
Compare positive and negative line-cycle conduction, power factor, low-order harmonics, charging ripple and semiconductor stress. State filter, load and sampling assumptions so waveforms can be reproduced.
Check conduction paths for both mains half-cycles and sign conventions; distinguish ideal and nonideal semiconductors; avoid claiming standards compliance without a stated standard and measured spectrum.
Baseline and experimental design
Describe each conduction interval and the roles of inductors, coupling capacitor, rectification devices and controlled switches.
Set up an AC input, high-frequency converter and battery-equivalent load with voltage/current sensing.
Evaluate startup, line-voltage variation, charging-load variation and realistic switching effects.
Metrics that distinguish performance
Mains voltage and current alignment and input power factor
Input current harmonic spectrum and THD under declared conditions
Inductor currents, switch voltage/current stress and converter duty ratio
Battery charging voltage, current and DC output ripple
Interpreting evidence
PFC assessment requires both power factor and harmonic distortion; one cannot infer compliance from an aligned waveform alone. Charging regulation must be evaluated at several battery voltages and load conditions.
Declare baselines, software versions, model fidelity and conditions; only present improvements that the supplied results directly establish.
Where this method fits
EV battery chargers, AC–DC conversion, high-power-factor rectifiers, converter efficiency studies and power-electronics coursework.
This article is an engineering checklist for reproducing and examining this class of simulation, not a claim that a particular result has been measured in the demonstration.
