中文摘要

Z源逆变器(ZSI)相比传统电压型和电流型逆变器具有显著优势,但其复杂的物理布局限制了工业应用。本文重点研究了Z源网络的硬件设计,旨在优化高频回路布局,抑制电压尖峰,提升系统可靠性与功率密度。

English Abstract

The Z-source inverters (ZSIs) have many advantages over the conventional voltage-fed and current-fed inverters, and extensive research works are conducing recently. However, relatively difficult physical layouts of the Z-source networks make them less attractive in the industry applications. A good hardware design is important to handle with the inherent long high-frequency loop in order to avoid ...
