The conventional energy sources available in the world are diminishing every year creating a huge difference between the demanded energy and the available energy. Efficient utilization of the ample renewable energy resources present in the world can be used to cover this extra demand. With the use of this renewable energy sources the levels of pollution and global warming can controlled to a lower level. A significant demerit with the renewable energy sources is their fluctuating nature. Hybridization technique is hence utilized to overcome this problem. This allows two sources to meet the load separately or simultaneously depending on the availability. In this paper a double input single output DC-DC converter is presented for stand-alone systems. The topology operates as a bootstrap circuit by employing the charging switches in case of only one input port powering or one input being short circuited and maintains the expected output voltage making the system fault tolerant.
