TY - JOUR AU - Chatchanayuenyong, Theerayuth PY - 2009 TI - A Fast Series Active Filter using Sliding Mode Control to Correct and Regulate Unbalance Voltage in Three-Phase System JF - American Journal of Engineering and Applied Sciences VL - 2 IS - 2 DO - 10.3844/ajeassp.2009.393.398 UR - https://thescipub.com/abstract/ajeassp.2009.393.398 AB - Problem statement: A Sliding Mode Controller (SMC) with fast reference voltage generation to correct and regulate unbalance voltage in three-phase system was proposed. Approach: The compensation algorithm was not based on three-symmetrical component decomposition so the controller can yield a fast response that was essential in such a critical real time control work. The reference voltages were fed to the SMC, which was a robust closed loop controller. Results: The proposed algorithm and control scheme of series active filter could correct and regulate unbalance voltage in three-phase system under arbitrary fault conditions of the utility supply. Conclusion: A design example and its simulation results proved the concept and validated the proposed algorithm.
