A series ac voltage regulator based on a new fundamental positive sequence calculation method, which is utilized to generate the compensation voltage reference, is introduced in this paper. The proposed method doesn't need hardware synchronization circuit and can perform the calculation of fundamental positive sequence component of the supply voltage in real time. Experiments based on DSPs were performed on the prototype,and the results indicate that the regulator based on the proposed approach works well under such conditions as source voltage sag, distortion and unbalance. Moreover, it is suitable for many kinds of load and has a good dynamic performance.
