Abstract :
This letter presents an improved control algorithm for the compensation of ac source voltage fluctuation. The proposed idea can be used to regulate both the overvoltage and undervoltage situations with only unidirectional energy transmission. Theoretical analysis has been achieved based on the power flow theory. A case study is demonstrated by means of a prototype experiment to prove its performance and effectiveness.
