An extended high step-up multi-input DC-DC converter

In this paper, an extended structure of a high step-up non-isolated multi-input DC-DC converter (MIC) is presented. The proposed structure, benefits from the both advantages of diode-capacitor and DC-DC boost converters. The main advantages of the suggested topology are possibility of throw continuous current from the input sources with various voltage-current characteristics, high voltage gain can be achieve without high duty cycle, low-voltage stress of power switches, and possibility of switching at high frequencies. Thus the topology is suitable for renewable sources applications like solar farms. In order to evaluate the performance of the proposed converter, simulation results by PSCAD/EMTDC software are presented.
