Abstract

This paper addresses optimal voltage and current quality in the sense of minimal Total Harmonic Distortion (THD) for a three-phase cascaded H-bridge inverter with a fundamental switching staircase modulation. THD minimization problems are formulated in time domain as constraint optimization ones in order to find theoretically optimal switching angles accounting for all switching harmonics. Provided are numerically obtained optimal switching angles and minimal voltage and current THD values for the overall output voltage dynamic range for a basic converter with two H-bridge modules per phase. While optimal three-phase inverter voltage THD solutions were already reported in literature, optimal current THD ones are supposed to be systematically presented for the first time.
