Abstract
A novel harmonic elimination PWM (HEPWM) technique for drives and static power converters is presented. The technique can be implemented on-line in real-time using a simple software algorithm, without resorting to any traditional off-line numerical techniques nor extensive lookup tables (LUTs). It is shown that the developed HEPWM technique can be implemented by calculating switching angles using simple algebraic equations and selecting switching states. In comparison with the previous reports which require the calculation of the switching angles in the first sextant, only the switching angles in the first half sextant are required. Simulation and experimental results are presented to confirm and demonstrate the features of the technique.
