With the development of renewable energy microgrid technology, DC energy conversion becomes the key topic in renewable energy conversion systems. This lecture, a three port DC converter with synthesis wireless power port connection has been proposed. The system has dual input ports which can connected to DC voltage and one load port partially isolated by LCL-LCL type wireless coupling tank. In addition, the proposed system allows the dual input port sources to have unbalanced voltage levels. The theoretical time domain analysis of the proposed topology and LCL coupling tank is presented in detail. The simulation model is built up in the PSIM environment, open loop simulation is carried out to obtain the power transfer haracteristics between the ultiple ports, and closed loop simulation is done to verify the efficiency of the designed control method. A 200W prototype was configured to demonstrate the performance of the proposed topology. Experimental results show that the proposed system can achieve a peak efficiency of 93.6% with load-independent constant current performance achieved.
