Abstract
This paper presents a new decoupling control scheme for paralleling two single-phase UPS with no control interconnection. Basing on the proposed control, the coupling between droop variables can be weakened, which leads to easiness of control and improvement of system performance. The simulation and experimental results show that the proposed control scheme can achieve good current sharing and improve the dynamic performance of the system.
