摘要

本文提出了一种典型的轻度混合动力汽车的48V转换链，该转换链具有增强的带状布局沟栅mosfet应用。mosfet技术允许调制内部器件参数，以改善器件对转换器应用的影响。考虑了48V总线中使用的几种转换器拓扑结构，以探索开关瞬态和热问题如何与功率器件性能相关联。正确选择MOSFET开关可以改善变换器的设计，提高整个低压混合动力汽车应用的可靠性。

Trench-Gate MOSFETs in 48V Platform for Mild Hybrid Electric Vehicle Applications

This paper presents a 48V conversion chain typical of a mild hybrid electric vehicle with enhanced strip-layout trench-gate MOSFETs applications. The MOSFETs technology allows modulating the inner device parameters to improve the device impact on the converter application. Several converter topologies used in the 48V bus are considered to explore how the switching transients and thermal issue are linked to power device performance. The correct choice of the MOSFET switch leads to improve the converter design and the reliability of the whole low voltage hybrid electric vehicle application.
