frequency, decreasing switching loss.The proposed modulation strategy was simulated on a 5-level cascaded H-bridge inverter.Simulation results verified its validity and superiority.Key words: electric inverters, switching systems, switching frequency, space vector pulse width modulation, 60° coordinate system
