Abstract

This paper presents development of a hardware simulator for the DC–AC inverters of electric compressors (e-compressors). In general, early-release EVs often feature a nominal battery voltage of around 400 V. However, EVs with a 400 V battery have drawbacks such as slow battery charging speeds and limited driving distances. To overcome these drawbacks, the nominal battery voltage has recently been increased from 400 V to around 800 V. Accordingly, research on electrical components applicable to EVs with an 800 V battery has been conducted. However, research on the DC–AC inverter used in the e-compressor, as a core component of an electric air conditioning system for EVs with 800 V battery, is insufficient. Therefore, the development of a hardware simulator of DC–AC inverters for the e-compressors used in EVs with an 800 V battery is proposed in this paper. The validity of the proposed hardware simulator is verified by experimental results.

用于电动压缩机的直流-交流变频器硬件模拟器
本文介绍了电动压缩机(e-compressors)直流-交流逆变器硬件模拟器的开发情况。一般来说,早期发布的电动汽车通常采用约 400 V 的标称电池电压。然而,采用 400 V 电池的电动汽车存在电池充电速度慢和行驶距离有限等缺点。为了克服这些缺点,最近已将标称电池电压从 400 V 提高到 800 V 左右。因此,对适用于 800 V 电池电动汽车的电气元件进行了研究。然而,作为配备 800 V 电池的电动汽车电动空调系统的核心部件,电子压缩机中使用的 DC-AC 逆变器的研究尚不充分。因此,本文提出开发一种用于装有 800 V 电池的电动汽车电动压缩机的直流-交流变频器硬件模拟器。实验结果验证了所提硬件模拟器的有效性。
