    Abstract: Systems, methods and devices which utilize Spread Spectrum Time Domain Reflectometry (SSTDR) techniques to measure degradation of electronic components are provided. Such measurements may be implemented while the components "live" or otherwise functioning within an overall system. In one embodiment, monitoring a power converter in a high power system is accomplished. In this embodiment, degradation of components within the power converter (e.g. metal-oxide-semiconductor field-effect transistors (MOSFETs), capacitors, insulated-gate bipolar transistors (IGBTs), and the like) may be monitored by processing data from reflections of an SSTDR signal to determine changes in impedance, capacitance, or any other changes that may be characteristic of components degrading. For example, an aging MOSFET may experience an increase of drain to source resistance which adds additional resistance to a current path within a power converter. Such a change is able to be analyzed monitored upon processing the reflected test signals.

One concept of the present disclosure is directed to a method of monitoring at least one capacitor bank having a plurality of steps. The method includes: receiving measurements indicative of voltages and/or currents on electrical lines coupled to the steps of the capacitor bank by corresponding contactors; receiving information indicative of the respective statuses of the contactors; timestamping the measurements and contactor status information; storing the timestamped measurements with corresponding timestamped contactor status information; determining a rate of change of a parameter indicative of or derived from at least the measurements associated with at least one of the steps in the capacitor bank; comparing the determined rate of change with a baseline rate of change to produce a deviation; determining if the deviation satisfies a criterion; and, if so, indicating the deviation satisfied the criterion.
