Battery Charger, when used in stand by application is not a standalone dedicated Battery Charger. Here battery charger along with a floating battery provide uninterrupted DC power supply to a critical load. This is Float-cum-boost battery charger or FCBC feeds the critical load without any break and also charges the discharged battery.
Though FCBC denotes “Float-cum-Boost” which clearly means single rectifier/converter for AC to DC conversion, but for higher capacity or higher load “Float-and-Boost” charger is used which has two rectifiers, one for feeding load and another for charging battery etc.
