Method of Optimization of a Periodic Step Waveform for Minimization of Total Harmonic Distortion.

Abstract

A method of optimization of a function of n variables under a constraint is developed. This method is applied to the optimization of N step voltage heights and the step width X in degrees (all step widths are equal) of a periodic step waveform so that the total harmonic distortion is minimized. Numerical techniques are used, and iterative algorithms are developed and implemented by a computer program, written in FORTRAN IV, for the USAMERDC CDC 6600 computer. Step waveforms with 3, 4, and 5 steps have been optimized. The procedure and the results are summarized.
