Elimination of the Inrush Current Phenomenon Associated with Single-Phase Offline UPS Systems

Energies, 2016
Critical load applications always rely on UPS systems to uphold continuous power during abnormal grid conditions. In case of any power disruption, an offline UPS system starts powering the load to avoid blackout.
