论文摘要
本文提出了一个新的拓扑，以连续传导模式（CCM）中未经修改的Greinacher电压乘数细胞（VMC）进行了改良的Greinacher电压乘数细胞（VMC）的新拓扑。拟议的拓扑结构可以迅速在组件和适当的占空比的压力下迅速获得高收益。此外，由于该转换器中使用的交错技术，该拓扑需要在CCM中的电感大小较小，同时保持输入电流的连续性。由于这些功能，该拓扑可用于许多可再生应用，例如PV，DC微电网等。本文介绍了设计过程和组件选择。此外，将提出的转换器模拟，以将20 V的输入电压转换为400 V的输出电压，输出功率为200W。最后，提供了实验结果以确认分析和仿真结果。
This paper proposes a new topology of a non-isolated two-phase interleaved boost DC-DC converters with modified Greinacher voltage multiplier cells (VMCs) in continuous conduction mode (CCM). The proposed topology can quickly achieve a high gain with low stress on components and proper duty cycle. Moreover, this topology requires a small inductance size in CCM while maintaining the continuity of the input current due to the interleaved technique used in this converter. Because of these features, this topology can be used in many renewable applications such as PV, DC microgrids, etc. The design procedures and component selection are presented in this paper. Furthermore, the proposed converter was simulated to convert an input voltage of 20 V to output voltage of 400 V with an output power of 200 W. Finally, experimental results have been provided to confirm the analysis and simulation results.
