| Abstract |
In this paper, a novel UPS topology based on the bidirectional converter is proposed. In the proposed UPS topology, a pre-regulator implemented by a tap-changer autotransformer is used for reducing the variation of mains voltage within +-5%. The transformerless bidirectional converter incorporated a small regulation inductor is only used for fine voltage regulation. It can improve the major shortcomings of the conventional bidirectional UPS. A steady state model is proposed for optimal parareters design. To test the performance of the proposed bidirectional UPS, a prototype is developed and tested. |
