Abstract:The junction temperature online measurement of power transistors is important for both the optimal operation and reliability of power electronics converters. The real-time junction temperature during the operation of a converter can be used to monitor the health of power modules to reduce losses and increase lifetime, including degradation monitoring, maintenance scheduling or even the implementation of active thermal control. This paper summarized different methods used to measure the junction temperature of power transistors in power electronic converters. Firstly, three main methods for the temperature evaluation of power semiconductor devices are presented and discussed, their advantages and disadvantages are also analyzed. On this basis, the online junction temperature measurement methods are classified into two categories: the methods based on thermal models, and the methods based on thermo-sensitive parameters. Then, these methods and their principles are summarized. In addition, the barriers and limitations of these methods for wider scale implementation are discussed. At last, the research trends are indicated. © 2018, Electrical Technology Press Co. Ltd. All right reserved.
