    Online double conversion is one of the main UPS topologies. Online UPSs provide the highest level of protection by isolating equipment from raw utility power by converting power from AC to DC and back to AC. Unlike other topologies, this double conversion method provides zero transfer time to battery for sensitive equipment. The online double conversion UPS topology is best applied to mission-critical equipment and locations where utility power is poor or highly unreliable.
