This paper presents a new two winding coupled inductor architecture for a semi magnetically coupled impedance source (SMCIS) inverter by connecting the coupled inductor windings in flipped gamma fashion. The proposed topology is derived from the conventional MCIS inverters. It can produce sinusoidal output voltage/current without using any shoot‐through operation and output LC filter, which improves the system reliability. Further, a doubly grounded feature, no start‐up inrush current, reduced component count, low input current ripple, continuous output currents, and small leakage currents are the major advantages of the proposed inverter. However, the proposed semi flipped gamma MCIS inverters still suffer from limited output voltage gain problem. The voltage‐boosting feature is added to the proposed inverter by connecting two converter modules in differential boost configuration through the embedded structure. The voltage‐boosting ability is the major advantage of this differential boost embedded configuration. It has flexibility in choosing a wide range of duty cycle operation from zero to one (whereas, the duty cycle was limited to 0.666 in case of semi‐Z‐source inverter [ZSI]). The modes of operation, design procedure, and feature comparisons of proposed inverters are discussed in this paper. Finally, the effectiveness of proposed inverters is validated through simulation and experimental results in terms of component count, voltage gain, and feature comparison.

具有成本效益的单相半翻转伽马型磁耦合阻抗源逆变器

本文通过以翻转伽马方式连接耦合的电感器绕组，提出了一种用于半磁耦合阻抗源（SMCIS）逆变器的新型两绕组耦合的电感器体系结构。提出的拓扑结构是从常规MCIS逆变器得出的。它可以产生正弦输出电压/电流，而无需使用任何直通操作和输出LC滤波器，从而提高了系统可靠性。此外，该逆变器的主要优点是具有双重接地功能，没有启动浪涌电流，减少了组件数量，输入电流纹波小，输出电流连续，漏电流小。但是，所提出的半翻转伽马MCIS逆变器仍然存在输出电压增益受限的问题。通过将两个采用差分升压配置的转换器模块通过嵌入式结构连接到拟议的逆变器中，可增强升压功能。升压能力是这种差分升压嵌入式配置的主要优势。它可以灵活地选择从零到一的宽范围的占空比操作（而对于半Z源逆变器[ZSI]，占空比被限制为0.666）。本文讨论了拟议中的逆变器的工作模式，设计程序和功能比较。最后，通过仿真和实验结果验证了所提出的逆变器的有效性，该仿真结果来自于组件数量，电压增益和功能比较。升压能力是这种差分升压嵌入式配置的主要优势。它可以灵活地选择从零到一的宽范围的占空比操作（而对于半Z源逆变器[ZSI]，占空比被限制为0.666）。本文讨论了拟议中的逆变器的工作模式，设计过程和功能比较。最后，通过仿真和实验结果验证了所提出的逆变器的有效性，该仿真结果来自于组件数量，电压增益和功能比较。升压能力是这种差分升压嵌入式配置的主要优势。它可以灵活地选择从零到一的宽范围的占空比操作（而对于半Z源逆变器[ZSI]，占空比被限制为0.666）。本文讨论了拟议中的逆变器的工作模式，设计程序和功能比较。最后，通过仿真和实验结果验证了所提出的逆变器的有效性，该仿真结果来自于组件数量，电压增益和功能比较。本文讨论了所建议的逆变器的特性，并进行了比较。最后，通过仿真和实验结果验证了所提出的逆变器的有效性，该仿真结果来自于组件数量，电压增益和功能比较。本文讨论了所建议的逆变器的特性，并进行了比较。最后，通过仿真和实验结果验证了所提出逆变器的有效性，该仿真结果来自于组件数量，电压增益和功能比较。
