How does a double conversion UPS work?
Double Conversion On-Line UPS is the same as the Standby UPS except that the primary power path is the inverter instead of the AC mains. Both the battery charger and the inverter convert the entire load power flow in this design, which causes undesirable heat and results in reduced efficiency.
