In this paper, a PWM Cuk AC-AC converter is modelled by using complex circuit DQ transformation whereby the equivalent model is obtained which has the complete information of the Cuk converter. Using the model, the dynamicc characteristics equations such as state equations is analytically obtained. Finally, the PSIM simulation show the validity of the modelling and analysis.

In this paper, a PWM Cuk AC-AC converter for power quality improvement of custom power is presented. The PWM Cuk AC-AC converter that is used in VVCF applications such as AC line conditioner, phase shifter is modelled by using complex circuit DQ transformation whereby the static characteristics equations such as voltage gain and power factor is analytically obtained. Finally, the PSIM simulation show the validity of the modelling and analysis.
