摘要

在混合动力汽车(HV)和电动汽车(EV)系统中使用了许多功率开关器件。对于HV/EV的未来发展，强烈要求比Si功率器件更高的性能，例如低导通电阻，高速，高工作温度。GaN功率器件是满足这些要求的有希望的候选器件。介绍了氮化镓功率器件的发展现状。讨论了氮化镓功率器件的可靠性。

GaN power device and reliability for automotive applications

Many power switching devices are used in a hybrid vehicle (HV) and an electric vehicle (EV) systems. For future development of the HV/EV, higher performances than Si power device, for example, low on-resistance, high speed, high operation temperature, are strongly required. GaN power devices are promising candidate for the requirements. Present status of the GaN power device development is presented. Reliability of the GaN power device was also discussed.
