English Abstract

A novel A-source impedance network is proposed in this letter. The A-source impedance network uses an autotransformer for realizing converters for any application that demand a very high dc voltage gain. The network utilizes a minimal turns ratio compared to other magnetically coupled impedance source networks to attain a high voltage gain. In addition, the proposed converter draws a continuous cu...

该拓扑通过自耦变压器实现高升压比,对阳光电源的组串式光伏逆变器(尤其是针对低压组件的升压级)以及储能系统(如PowerTitan系列中DC-DC升压环节)具有重要参考价值。其高增益、低匝数比的特性有助于减小磁性元件体积,提升功率密度,并降低电磁干扰。建议研发团队评估该拓扑在提升逆变器效率及降低系统成本方面的潜力,特别是在需要宽输入电压范围的户用及工商业光伏场景中进行可行性验证。
