Abstract

In this paper, the multi-mode operation of the on-line UPS system is investigated and corresponding control strategies are proposed. The proposed control strategies are able to achieve the seamless transition in traditional normal mode, PV-aided normal mode, enhanced eco-mode and burn-in test mode. At the same time, the uninterruptible load voltage is guaranteed during the transition between these modes. Furthermore, the stability of enhanced eco-mode and burn-in test mode is studied by small signal analysis. Finally, extensive experimental results are provided to validate the effectiveness of the proposed methods.
