摘要
本文提出了一种新型超增益立方（UGC）直流-直流转换器，用于将光伏和燃料电池并入电网。拟议的 UGC 共有 12 个组件，包括一个开关。文章解释了两种模式下转换器的稳态运行，并推导出必要的方程式。研究了寄生元件对 UGC 直流电压增益的影响，最后通过状态空间平均技术验证了 UGC 转换器的稳定性。优化元件数量、超电压增益、输入和输出端连接到同一地线、单开关、输入电流连续是 UGC 转换器的主要方面。利用硬件结果对输出电压为 325V 的 300W 原型进行了测试和验证。
A Novel Transformer Less Ultra Gain DC-DC Converter for Renewable Micro Energy Sources
This article proposes a novel Ultra Gain Cubic (UGC) DC-DC converter for integrating PV and Fuel cell into the grid. The proposed UGC has 12 components in total, including asingle switch. The steady-state operation of the converter in both modes were explained and necessary equations were derived. The impact of parasitic elements on the UGCs DC-voltage gain is investigated and finally the stability of the UGC converter is verified through state space averaging technique. Optimized number of components, Ultra voltage gain, input and output terminals are connected to same ground, Single switch, input current continuous are the key aspects of the UGC converter. A 300W prototype with a 325V output voltage is tested and validated using hardware results.
