Zusammenfassung:	In this paper, the characteristics of an AC line conditioner based on three-phase PWM Cuk AC-AC converter are analyzed. The PWM Cuk AC-AC converter is modeled by using complex D Q circuit transformation whereby the important characteristic equations such as voltage gain, input power factor, and the interested voltages and/or currents can be analytically obtained. Moreover, AC analysis is given by perturbing the complex DQ circuit and thus the linearized model is obtained for control purpose. Finally, the digital simulation with PSIM shows the validity of the modeling and analysis.
