A Non-Isolated High Step-Up Interleaved DC-DC Converter with Diode-Capacitor Multiplier Cells and Dual Coupled Inductors
摘要：
本文提出了一种非隔离式高升压DC-DC变换器。建议的转换器是由一个交错的结构和二极管电容倍增器单元接口的低压可再生能源的高压配电母线。由于采用耦合电感器和二极管电容器单元，上述拓扑可以提供非常高的电压增益。耦合电感连接到二极管-电容乘法器单元，以实现输出侧的交错储能。此外，所提出的拓扑结构提供了连续的输入电流，且功率器件上的电压应力较低。减少了二极管的反向恢复问题。这种拓扑结构可以通过调整耦合电感的匝数比以减小的占空比操作。最后，将该拓扑与其它变换器进行了性能比较.文中介绍了设计考虑、工作原理、稳态分析、仿真结果和实验验证。因此，一个500-W的硬件原型，输入电压为30-V，输出电压为1000-V的构建来验证性能和理论分析。
英文摘要：
In this paper, a non-isolated high step-up dc-dc converter is presented. The proposed converter is composed of an interleaved structure and diode-capacitor multiplier cells for interfacing low-voltage renewable energy sources to high-voltage distribution buses. The aforementioned topology can provide a very high voltage gain due to employing the coupled inductors and the diode-capacitor cells. The coupled inductors are connected to the diode-capacitor multiplier cells to achieve the interleaved energy storage in the output side. Furthermore, the proposed topology provides continuous input current with low voltage stress on the power devices. The reverse recovery problem of the diodes is reduced. This topology can be operated at a reduced duty cycle by adjusting the turn ratio of the coupled inductors. Moreover, the performance comparison between the proposed topology and other converters are introduced. The design considerations operation principle, steady-state analysis, simulation results, and experimental verifications are presented. Therefore, a 500-W hardware prototype with an input voltage of 30-V and an output voltage of 1000-V is built to verify the performance and the theoretical analysis.
