Harmonic analysis of SVM and experimental verification in a general purpose induction motor test rig

This paper focuses primarily on the harmonic analysis of space vector modulation (SVM) line to line voltage waveforms generated using an 80C166 microcontroller. The study is based on practical harmonic measurements of the line to line SVM voltage waveforms using a FFT analyser and simulation results. This paper shows how such an analysis can be used as part of the characterisation of a general purpose 3 phase 7.5 kW induction motor PWM voltage source inverter (VSI) test rig.
