本文提出了一种阻抗源（或阻抗馈电）功率变换器（简称Z源变换器）及其控制方法，实现了直流-交流、交流-直流、交流-交流和直流-直流功率变换。Z源转换器采用独特的阻抗网络（或电路）将转换器主电路耦合到电源，从而提供在分别使用电容器和电感器的传统电压源（或电压馈电）和电流源（或电流馈电）转换器中无法获得的独特特征。Z源变换器克服了传统电压源变换器（简称V源变换器）和电流源变换器（简称I源变换器）在概念和理论上的障碍和局限性，提供了一种新颖的功率变换概念。Z源概念可应用于所有DC-AC、AC-DC、AC-AC和DC-DC功率转换。为了描述工作原理和控制，本文重点介绍了一个例子：Z源逆变器的DC-AC功率转换所需的燃料电池应用。仿真和实验结果证明了新的功能。
This paper presents an impedance-source (or impedance-fed) power converter (abbreviated as Z-source converter) and its control method for implementing DC-to-AC, AC-to-DC, AC-to-AC, and DC-to-DC power conversion. The Z-source converter employs a unique impedance network (or circuit) to couple the converter main circuit to the power source, thus providing unique features that cannot be obtained in the traditional voltage-source (or voltage-fed) and current-source (or current-fed) converters where a capacitor and inductor are used respectively. The Z-source converter overcomes the conceptual and theoretical barriers and limitations of the traditional voltage-source converter (abbreviated as V-source converter) and current-source converter (abbreviated as I-source converter) and provides a novel power conversion concept. The Z-source concept can be applied to all DC-to-AC, AC-to-DC, AC-to-AC, and DC-to-DC power conversion. To describe the operating principle and control, this paper focuses on an example: a Z-source inverter for DC-AC power conversion needed in fuel cell applications. Simulation and experimental results are presented to demonstrate the new features.
