Active and reactive current decoupled control strategy applied to a single-phase BTB converter

This paper presents a comparison of two control strategies applied to a Single-Phase Back to Back converter. Both techniques use two loops: one inner current loop and an outer voltage loop. The first control strategy is based on a classical PI control. The second one uses a control scheme to decouple the active and reactive component of the input current, obtaining a better steady state and dynamic response of the system. The performance is verified with simulation and experimental results.
