Abstract :
The authors show how power circuit parameters and waveforms can be systematically estimated offline from recorded segments of accessible waveforms. The iterative nonlinear least-squares algorithm described combines simulation and analysis to assess fit, determine sensitivities, and tune parameters. Pitfalls, and strategies for overcoming them, are discussed and illustrated.<>
