Abstract
Disclosed herein are methods, systems, and devices for supporting the transition to lithium-ion batteries and leveraging the value that lithium-ion batteries offer in double conversion uninterruptible power supply (UPS) applications. According to one embodiment, a UPS system includes an alternating current (AC) to direct current (DC) rectifier configured to be electrically coupled with an AC source, a DC to AC inverter configured to be electrically coupled with an AC load, a DC bus electrically coupled between the AC to DC rectifier and the DC to AC inverter. The UPS system also includes a diode electrically coupled between the DC bus and a first battery cell of a plurality of battery cells, and a by-pass relay having a first terminal electrically coupled with an anode of the diode and a second terminal electrically coupled with a cathode of the diode.
