An isolated two-input power converter for hybrid power supply systems is proposed in this paper. The proposed converter is derived from the integration of a forward converter and a Cuk converter. The grid and solar energy are used as the two input power sources. The power flow of each energy source can be independently controlled. Also, the proposed converter can be operated with single power source or dual power sources. Once the maximum available solar power isinsufficient for the load, the converter would automatically complement the power demand by drawing power from the grid side. A prototype system is constructed and some experiments are carried out to evaluate the validity and performance of the proposed twoinput power converter. From the experimental results, one can see that the proposed converter can provide a stable output with 90V /3.85A and the efficiency is about 90%.
