| Abstract | With the emerging installations of multitype renew- able energy sources and energy storage elements, the dc electronic distribution systems in residential buildings (dc nanogrid) are be- coming an alternative future system solution, achieving a zero net- energy consumption and optimized power management. The con- cept of the energy control center (ECC), which interconnects the dc system to the traditional ac utility grid, is introduced, and the operation function of ECC converter suitable for dc nanogrid ap- plication is defined. This paper investigates a two-stage topology using a full bridge in series with a bidirectional synchronous recti- fier dc–dc converter as a single-phase ECC for dc nanogrid, with a significant reduction of the dc-link capacitor value. The operation analysis and the design of passive components are provided.Abidi- rectional control system and the design process are also presented in terms of the system requirement and the small dc-link capacitor |
