Characteristic Analysis of Static Var Compensator Using Three Phase PWM Cuk AC-AC Converter

3상 PWM Cuk AC-AC 컨버터를 이용한 정지형 무효전력보상기의 특성해석

In this paper, a static var compensator using PWM Cuk AC-AC converter is presented. The PWM Cuk AC-AC converter is modelled by using complex circuit DQ transformation whereby the basic condition to be used as a var compensator is derived and the static characteristic equations such as input current and reactive power is analytically obtained. Finally, the PSIM simulations show the validity of the modelling and analysis.
