A Novel Approach for Evaluating Performance of Discontinuous Pulse Width Modulation Schemes for Three Phase Voltage Source Inverter

A simple approach is presented for obtaining the switching loss factor (SLF) and quality factor (QF) used as merit factors for evaluating performances of various discontinuous pulse width modulating (DPWM) signals derived from a generalized discontinuous pulse width modulation scheme. This approach precludes the need for rigorous calculation of inverter losses as employed in most traditional methods. Results are given to validate performance criteria and to show areas of application
