A Double-Conversion UPS continuously rectifies incoming AC to DC and then inverts it back to clean AC, so the load is always fed from the inverter and fully isolated from utility disturbances. This online topology gives the best power quality and seamless transfer to battery, at some cost in efficiency, and is the standard choice for critical data-center loads.
