“…If a deviation is detected, one can conclude that degradation has taken place. This deviation can also be a result of another failure mechanism observed in actual systems [28,29], which is thermal grease degradation. The mechanisms such as the grease pump-out and dry-out also induce an increase in the grease thermal resistance [30] and the heat flux through the HFS.…”

This paper proposes and investigates the application of the gradient heat flux sensor (GHFS) for measuring the local heat flux in power electronics. Thanks to its thinness, the sensor can be placed between the semiconductor module and the heat sink. The GHFS has high sensitivity and yields direct measurements without an interruption to the normal power device operation, which makes it attractive for power electronics applications. The development of systems for monitoring thermal loading and methods for online detection of degradation and failure of power electronic devices is a topical and crucial task. However, online condition monitoring (CM) methods, which include heat flux sensors, have received little research attention so far. In the current research, an insulated-gate bipolar transistor (IGBT) module-based test setup with the GHFS implemented on the base plate of one of the IGBTs is introduced. The heat flux experiments and the IGBT power losses obtained by simulations show similar results. The findings give clear evidence that the GHFS can provide an attractive condition monitoring method for the thermal loading of power devices.

“…This may affects module's reliability and may cause early failures. In field, IGBT modules are subjected to a multitude of stresses [1,[17][18][19][20]. IGBT modules may fail due to random system overstress events such as overvoltage and overcurrent.…”

“…The second part of the paper provides a detailed discussion on IGBT modules' failures, accelerated lifetime testing, lifetime modes, and degradation characterization associated to electro-thermal stresses. Since a significant portion of IGBT modules' field failures are attributed to extensive electro-thermal stresses due to temperature cycling [1,[17][18][19][20]. The paper is organized as follows.…”
