A new DC converter in DC micro-grid applications is studied and proposed in this paper. The studied converter is based on the series connection of full-bridge resonant circuits to achieve the main advantages of low voltage rating of power devices, wide zero-voltage switching losses on active devices, possible no reverse recovery current loss on rectifier diodes and low current rating on secondary side. The system analysis, circuit characteristics and design considerations are discussed. Experimental results are given and discussed to demonstrate the characteristics and usefulness of the studied circuit.
