In this study, a novel high‐step‐up converter is proposed with a new hourglass‐shaped impedance network (HIN). Due to the short lifetime of electrolytic capacitors (ECs), the proposed converter uses nonelectrolytic capacitors (NECs), which however can realize all ECs' features. Besides, the proposed converter has low capacitor voltage stresses, ensuring it could be electrolytic‐capacitors‐free. With this feature, the proposed high step‐up converter has smaller size, lighter weight, smaller parasitic resistance, and longer operation life than the conventional ones with ECs. In this paper, detailed operational principle and performance of the proposed converter are presented, to demonstrate its advanced features. Simulation and experimental studies are also carried out, which validate the feasibility and effectiveness of the proposed converter.

基于沙漏形阻抗网络的低电压非电解电容器高升压转换器

在这项研究中，提出了一种具有新型沙漏形阻抗网络（HIN）的新型高升压转换器。由于电解电容器（EC）的使用寿命短，因此建议的转换器使用非电解电容器（NEC），但是可以实现所有EC的功能。此外，拟议的转换器具有较低的电容器电压应力，从而确保了它无需电解电容器。凭借此功能，与传统的EC转换器相比，拟议的高升压转换器具有更小的尺寸，更轻的重量，更小的寄生电阻以及更长的使用寿命。在本文中，提出了拟议的转换器的详细工作原理和性能，以证明其先进的功能。还进行了仿真和实验研究，验证了所提出的转换器的可行性和有效性。
