Title:
HIGHLY-EFFICIENT UPS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/143883
Kind Code:
A1
Abstract:
A highly-efficient UPS system. The UPS system comprises a rectification module (20) and an inversion module (10), wherein the input end of the rectification module (20) is connected to the L end of an AC power supply, the input end of the inversion module (10) is connected to the L end of the AC power supply and the output end of the rectification module (20) respectively, and a stable AC voltage is output by the output end of the inversion module (10). By directly outputting the input alternating current to the outside, the input voltage is compensated using the energy output by a bus to output a stable AC voltage, so that double conversion is conducted on partial alternating current, so that the energy loss is reduced, the conversion efficiency is increased, and the full power operation is not required in a rectification part, thus reducing the rectification part.
