MITIGATION OF HARMONIC DISTORTION USING OPTIMUM PHASE-SHIFT MULTIPLE PARALLEL INVERTERS

Journal of Engineering and Sustainable Development, 2018
It is clear that the harmonics in power systems have many negative impacts and therefore it is inevitable to reduce their amount to the accepted level and one of the interesting approach to reduce the harmonic distortion is to synchronize phase-shifted ...

Research on Neutral Point Drifting Technology Based on the Same Harmonic Distribution of Line Voltage

Kongzhi Yu Xinxi Jishu, 2011
Neutral point drifting technology based on the same harmonic distribution of line voltage is proposed. With the optimization of carrier phase-shifted angle and frequency modulation ratio, the harmonic distribution of three line voltages can be consistent.
