A New PWM Control based on an Optimized Zero Sequence Component injection: Application in a Two-Level Inverter [PDF]
IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021 In this paper, a new optimization problem is proposed for improvement of PWM control of an inverter that supplies a generic RLE load. Two objectives functions are studied separately: Weighted Total Harmonic Distortion (WTHD) of load voltages and total losses.
