    Traditionally, condition monitoring of power semiconductor modules has been based on electrical measurements. Acoustic emission has been utilized for condition monitoring in many other applications, but is an unknown phenomenon in power semiconductor modules. In this paper, the authors present an experimental setup used to show that acoustic emission does occur because of the switching of ...

    a condition monitoring tool, the best-known being possibly bearing failure detection and rotational machine control. Acoustic signals in the power modules are low, and significant damping is induced by the plastic parts of the power modules. As of now, in power semiconductor modules, acoustic emission is a relatively unknown phenomenon, and ...

    In this paper, recording of acoustic emission during real operations is used for non-invasively detecting the aging of a power seminconductor module due to power cycling. The presented method is very simple and particularly attractive because of non-invasiveness and potential low-cost features, which can enable straightforward adoption in condition monitoring of power electronic devices.

    A condition monitoring system would help to alleviate these concerns, but for the time being, there is no generally accepted and widely adopted method for power electronics. Acoustic emission is used as a failure precursor in many applications, but it has not been ... determined whether an acoustic-emission-based condition monitoring method can ...

    In this paper, a novel potential method based on acoustic or stress parameter is proposed. The mechanical stress wave (MSW) and electromagnetic wave (EMW) generated from power metal-oxide-semiconductor field-effect transistor (MOSFET) are analyzed under low voltage condition for the first time.

  9. correctly interpreting the monitored emission. Acoustic emission has bee proven to happen n during a current switching, and that it differs claimed between a healthy power module and a failed power module in [12] and [14]. However, in these papers only the acoustic emission of an IGBT subject to short-circuit was investigated.

    based on acoustic emission was presented and used to detect any physical damage in a power module packaging. It is worth underlining that it enables one to estimate the state of aging of a power module. Then, CM methods based on the optical properties of the semiconductor power devices were presented, including temperature estimation.
