SUMMARY A highly accurate and robust Marquardt least squares method, which simultaneously solves a set of nonlinear equations, is employed to analyse the accuracy of the Heidler function parameters recommended by IEC 62350–1 Ed. 2. In addition, Heidler function parameters for reproduction of various frequently used standardized waveshapes are provided. The possibility of using the Marquardt least squares method for fitting Heidler function to actual measured data is explored. Copyright © 2011 John Wiley & Sons, Ltd.
