In this paper, a novel feedback linearization sliding mode controlled parallel active power filter with indirect current control approach is presented in the three-phase three-wire grid. The feedback linearization indirect current controlled method is used to implement the DC side voltage regulation while a novel integral sliding mode controller is applied to reduce the total harmonic distortion of supply current. Since traditional unit synchronous sinusoidal signal calculating methods are not applicable when supply voltage contains harmonic, a novel unit synchronous sinusoidal signal computing method based on synchronous frame transforming theory is presented to overcome this disadvantage. Simulation results verify that the DC side voltage is well stable at the given value and responds fast to the external disturbance. Comparison is also made to show the advantages of the novel unit sinusoidal signal calculating method and super harmonic treating property of the designed active power filter.
