N2 - In this paper, a new non-isolated multi-input step-up converter is presented. By implementing a new switching algorithm in the proposed topology, the converter output voltage, as well as the power absorbed from each source, can be controlled independently, resulting in a simple controller, which is a distinctive virtue for this converter in comparison to similar multi-input converters. Current sharing between various sources is achieved independently. No need to control different parameters of switches' gate-source voltage such as the delay between switches and thus independent maximum power point tracking (MPPT) algorithm can be used for each input source. Providing soft-switching condition and transferring power from all inputs to the load independently are other features of this converter. Operating modes of the converter as well as experimental results obtained for a 300 W prototype for supplying stand-alone load are presented.
