目前，功率变换器的黑盒行为模型在系统级分析中越来越受到关注。这些模型可用于评估由商用变流器组成的电力电子系统的响应，因为它们可以通过分析实际变流器响应来完全参数化。最近提出了第一个功率变换器的黑盒模型，但它们都是面向DC-DC变换器的。然而，三相电压型逆变器通常应用于目前的电力电子系统，如飞机电源系统，和黑盒建模方法尚未提出这类变换器。提出了一种三相电压型逆变器的大信号黑箱建模方法。该模型的辨识是基于变换器的瞬态响应分析，这是通过一组简单的实验和易于使用的拟合算法得到的。所提出的方法进行了实验验证的5千瓦实际逆变器上应用于飞机电源系统测试台。
Nowadays, black-box behavioral models of power converters are becoming interesting for system-level analysis. These models can be used to evaluate the response of power electronics systems which are composed of commercial converters, since they can be fully parameterized by analyzing the actual converter response. First black-box models of power converters have been recently proposed, but all of them are oriented to DC-DC converters. However, three-phase voltage source inverters are usually applied in current power electronics-based systems, such as aircraft power systems, and a black-box modeling method of this kind of converters has not yet been proposed. In this paper a large-signal black-box modeling method of three-phase voltage source inverters is proposed. The identification of the model is based on the analysis of the converter transient response, which is obtained by means of a set of simple experiments and easily usable fitting algorithms. An experimental validation of the proposed method has been carried out on a 5 kW actual inverter applied on an aircraft power system test bench.
