  • Patent Pending

A measurement method/device that measures the acoustic noise near an operating power converter and predicts the remaining useful life of the converter. The acoustic noise is generated by the switching events of power semiconductors. Compared with the state-of-the-art aging detection or failure detection methods, this method does not require inserting a special-designed detection circuit near the power switches.
