Experimentally Investigation of Some Facilities Provided by Hybrid UPSs

İngilizce (OpenAlex)

Uninterruptible power supplies (UPS), which are used to provide uninterrupted and high-quality energy to the consumer, have also changed in parallel with the developments in the energy sector. In the process, the efficiency of conventional UPSs has increased by developments in power electronics elements, and the dimensions and weights have been reduced with the transformerless UPSs. Recently, UPS systems, which are not indifferent to the developments in renewable energy systems, have achieved a hybrid structure using the energy obtained from these systems. In this study, various advantages of these UPSs are examined experimentally over a sample hybrid UPS via input/output current/voltage waveform. In this context, several features of hybrid UPSs such as feeding the load only through the PV system, supplying the load from the grid and PV system, adapting to on-grid/off-grid operation were examined. The results show that hybrid UPSs are promising in providing uninterrupted, high quality, and efficient energy.
