Ran, L. and Holdsworth, L. and Putrus, G. A. (2002) 'Dynamic selective harmonic elimination of a three-level inverter used for static VAr compensation.', IEE proceedings : generation, transmission and distribution., 149 (1). pp. 83-89.
The paper investigates the harmonic interaction between the AC and DC sides of a 3-level inverter used as a static synchronous VAr compensator (STATCOM). It is illustrated that due to the 3rd harmonic voltage across each DC side capacitor. the conventional selective harmonic elimination modulation (SHEM) may not actually eliminate the target harmonics when the system is on load. A new modulation method, which dynamically adjusts the switching angles according to the operating point, is proposed to overcome this difficulty. The proposed method is verified using simulation and experimental test.
