This paper provides a comprehensive study on the isolated interleaved boost with coupled inductors (IBCI) converter, which is suitable for high step-up and high efficiency applications, such as fuel cells, photovoltaic modules, etc. Based on the analysis of the operating principle of the IBCI converter, three key design parameters of it are studied carefully, which will largely influence the step-up capability and the efficiency of the converter operating at rated power point. Therefore, a parameter optimization design method is proposed in this paper. By theoretically calculating the voltage gain and the efficiency at the rated power point, the proposed design method can obtain the optimal design parameters that not only can meet the need for high step-up capability, but also achieve a high efficiency. Simulation experiments have been carried out in this paper to verify the effectiveness of the proposed design method. A prototype is also being established and tested to validate this method.
