Abstract
In this paper, a double input DC-DC converter based on modified Z-source converter is suggested for standalone PV/Battery system application. The configuration of double input DC-DC converter under one port powered off is presented to solve problem of randomness and intermittency in distributed power source. In the proposed topology, the input DC voltage is boosted and achieved higher voltage gain with lower voltage stress on power switches. Other merits of the proposed converter are that it operates with wide range of load, and input DC voltage sources supply DC load individually or simultaneously. The configuration of the proposed double input DC-DC converter is introduced and then, its operation principle is analyzed in detail. Switches voltage and current stresses are studied and then, calculation of voltage gain is performed for different states of the converter. Finally, simulation results are given to verify the theoretical analysis and performance of the suggested DC-DC converter.
