主 题：IGBT health monitoring temperature sensitive electrical parameter(TSEP) three-level inverters reliability
摘 要：Requirements of the Internet of things for the network includes the ability to monitor the equipment and ***,the reliability of a power electronics converter has raised concerns of both academia and *** particular,power semiconductor devices are continuously exposed to excessive stress while being designed with high power handling capability and are considered as the most fragile component in power converters suffering from a high failure *** to find an effective monitoring method which is also helpful for the Internet of Things and improve the reliability of a three-level neutral-point-clamped power inverter,an in-situ health monitoring method is proposed by harnessing the inverter operational characteristics and degradation sensitive electrical parameters to address the IGBT wire bonding *** zero voltage state provides an inherent redundant feature that allows for a power switch to be diagnosed during its normal operation in a neutralpoint-clamped power *** proposed prognostic approach obtains both the wire bonding failure features and junction temperature from the terminals of an IGBT module,which is regarded as non-invasive on-line health *** system performance can be affected by the designated testing point and testing window,which is discussed and experimentally *** proposed technique allows unhealthy wire bonding in IGBT modules online monitoring during the operational period of the *** the proposed in-situ health monitoring of IGBT modules can be used for the industrial Internet of things.
