Abstract: A health signature of each switching device in a control system is estimated using system parameters such as a DC-link voltage, three-phase voltages, three-phase currents, and temperature. The switching devices can be implemented as transistors, and a health signature for each transistor may be an on-state resistance or an on-state voltage of the transistors. For example, the on-state resistance for a metal-oxide-semiconductor field-effect transistor (MOSFET) functions as a health signature. Alternatively, the on-state voltage is used as a health signature for an insulated-gate bipolar transistor (IGBT). Additionally, a junction temperature is estimated for each transistor. Using the estimated health signatures and the junction temperatures, the remaining useful life of each transistor is estimated.

Abstract: In some examples, there is provided a method for a storage controller to receive a request to write data at a virtual location, writing data at the next free physical location in sequence, writing metadata correlating the virtual location with the physical location at the physical location, and writing a counter at the physical location. The recorded metadata can be used to re-construct the mapping between a given physical location and its corresponding virtual location if the virtual block address is somehow lost. The recorded counter can be used to determine the most recently recorded mapping between the virtual location and physical location, thereby resolving any discrepancies between earlier recorded metadata.
