The digest introduces a novel DC-DC converter archtecture based on adder transformer configuration. The unique transformer structure comprises of multi primaries, each connected to multiple resonant inverters and single turn common secondary. The architecture facilitates natural current sharing between mutiple modules without the use of additional hardware or complex control techniques. Moreover, soft switching for full load voltage and power range for all switches is achived. A 1kW experimental prototype is presented that demonstrtes a peak efficiency of 97.2% and lowest efficiency of ~90%
