The present disclosure provides a switched reconfigurable multi-converter multi-source energy storage system configuration for electrified vehicles comprising of multiple dc/dc power converters, multiple energy sources, a mode selector switching module further comprising a plurality of controllable switches and a controller. A method of switching to reconfigure the multi-converter multi-source energy storage system during the dynamic events of variable power demand or regeneration in an electrified vehicle is disclosed. Furthermore, a power flow control scheme for executing the dynamic switching methods of reconfiguration to maneuver the flow of power within the system during different scenarios of forward power delivery or reverse power accumulation is disclosed. The controllable switches are methodically activated or deactivated to couple or decouple the energy sources to or from the input side of the dc/dc power converters by means of necessary activation or deactivation signals from the controller. Nevertheless, a fault tolerant control scheme is disclosed to ensure fail-safe operation of the switched reconfigurable system during the occurrence of fault in any of the dc/dc power converters.
