Abstract	A novel phase-shifting harmonic elimination technique (PSHE) in PWM static VAr compensators (PSVCs) is proposed in this paper. By making the gating signals of the three phases shifted by T/sub s//3 in turn, the harmonics of (3k-2)f/sub s/-f and (3k-l)f/sub s/+f are eliminated from the compensating current. Compared with the previously presented compensator, it can work at a lower frequency with less harmonics. Moreover, it has the advantages of easy implementation and rapid response. The operating principle of the proposed concept is analyzed, and is finally verified by simulations and experiments.
