Abstract

This paper introduces a modified double dual boost converter with the same voltage and current transfer ratio as the cascade type. However, the proposed converter can use substantially smaller capacitances and be applied in different applications such as distributed generation and microgrids. This paper presents the steady-state analysis of the proposed converter in continuous conduction mode. The ripples on capacitor voltage are deeply analyzed to provide design guidelines. A comparison of the proposed converter against the traditional double dual boost converter is discussed. The capability of effectively reducing the output voltage ripple, even with small individual capacitances, is evaluated via simulation. Finally, experimental results are provided to verify the principle of the proposed converters in different operating conditions.
