Controller Design of Static Var Compensator Using Three Phase PWM Cuk AC-AC Converter

3상 PWM Cuk AC-AC 컨버터를 이용한 정지형 무효전력보상기의 제어기 설계

This paper presents controller design of a static var compensator using PWM Cuk AC-AC converter. The PWM Cuk AC-AC converter is modelled by using complex circuit DQ transformation and perturbed around the operating point whereby the small signal system characteristics is analytically obtained. Finally, the PSIM simulations show the validity of the modelling and analysis.
