Aalborg Universitet Selective harmonic control for power converters

This paper proposes an Internal Model Principle (IMP) based Selective Harmonic Controller (SHC) for power converters. The proposed SHC offers an optimal control solution for power converters to mitigate power harmonics. It makes a good trade-off among cost, complexity and performance. It has high accuracy and fast transient response, and it is cost-effective, easy for real-time implementation, and compatible for design rules-of-thumb. An application on a threephase PWM converter has confirmed the effectiveness of the proposed control scheme in terms of harmonic mitigation.
