论文摘要
本文提出了一种用于汽车应用的新型多级逆变器。拓扑由模块化DCDC转换器和一个TAP选择器组成，其中DC-DC转换器提供了多个DC输出级别，而Tap Selector通过从DC-DC转换器中选择不同的DC输出信号来产生AC信号。为了产生DC级，DC-DC转换器由模块化结构组成，其中模块以串联连接。新颖的是，这些模块在AC域中磁性磁膜连接，并在DCONAR中进行电。由于模块中低功率开关的使用，提出的结构可提供高效率。此外，DC-DC转换器能够自动平衡其模块，因此不需要大型电容器，该电容器产生高功率密度。构建了所提出的转换器的原型，并使用模拟以及实验结果来验证发现。
This paper proposes a novel multilevel inverter for automotive applications. The topology consists of a modular DCDC converter and a tap selector, where the DC-DC converter provides several DC-output levels and the tap selector produces an AC signal by choosing different DC-output signals from the DC-DC converter. To produce the DC-levels, the DC-DC converter consists of a modular structure where the modules are connected in series. The novelty is that the modules are connected both, magnetically in the AC-domain and electrically in the DCdomain. Due to the usage of low power switches in the modules, the proposed structure provides high efficiency. Furthermore, the DC-DC converter is capable of self-balancing its modules and thus does not require large capacitors which yields a high power density. A prototype of the proposed converter is built and simulation, as well as experimental results, are used to verify the findings.
