摘要

在用于混合动力和电动汽车的逆变器技术中,对重量轻、结构紧凑、体积小、高功率密度和高效率等性能的要求很高,因为它们会影响汽车的生产成本和燃油经济性。实现可靠、廉价、高响应速度的设备,与电路设计、小型化和适当选择元件密切相关,已成为电子学科学研究的主要课题之一。实现这些目标的主要障碍之一是电感器和电容器的体积庞大。这些转换器拓扑结构的基本构件用于减少输入电流和输出电压纹波,而纹波与电池的热应力密切相关,会影响电池的使用寿命。本研究为混合动力汽车提出了一种基于氮化镓的多器件交错升压转换器(MDIBC)拓扑结构。在不同开关频率下的两个突出案例研究中,对该拓扑结构的功率损耗、效率、电流和电压纹波以及无源元件的尺寸进行了研究。在这两种情况下,在不影响效率的前提下,通过减小无源元件的值来降低电流和电压。在基准转换器中保留无源元件的情况下,效率达到了 97.34% 至 97.83%。

Modified all-GaN multidevice interleaved boost converter topology for hybrid electrical vehicles and its miniaturization

In inverter technology for hybrid and electric vehicles, some properties, such as low weight, compactness, small size, high power density, and high efficiency, are highly required because they affect vehicle production costs and fuel economy. Bringing reliable and cheap devices with high response rates into being, which is in close relation with circuit design, miniaturization, and appropriate selection of components, have become one of the main topics of scientific research in electronics. One of the main obstacles to achieving these goals is the bulkiness of inductors and capacitors. These essential building blocks of the converter topology are used to reduce input current and output voltage ripples, which are closely related to thermal stress in batteries, affecting their lifespan. This study proposes a GaN-based multidevice interleaved boost converter (MDIBC) topology for hybrid vehicles. The topology is investigated in terms of power loss, efficiency, current and voltage ripples, and size of passive components under two salient case studies at various switching frequencies. In both cases, current and voltage are reduced by smaller values of passive components without sacrificing efficiency. Efficiencies ranging between 97.34 and 97.83%, are achieved with passive components remaining in the benchmark converter.
