Latest Patents

One of Stuart's latest patents is titled "Estimation of Life of Switching Devices." This invention involves estimating a health signature for each switching device in a control system by utilizing system parameters such as DC-link voltage, three-phase voltages, three-phase currents, and temperature. The health signature can be represented by the on-state resistance or on-state voltage of transistors, such as metal-oxide-semiconductor field-effect transistors (MOSFETs) and insulated-gate bipolar transistors (IGBTs). Additionally, the patent includes methods for estimating the junction temperature of each transistor, which aids in determining their remaining useful life.

Another significant patent is "Motor Winding Fault Diagnosis." This invention relates to systems and methods for detecting winding faults and assessing their severity in brushless direct current motors before failure occurs. The methods employed include time domain-based sequence component analysis, fast Fourier transform analysis, and Hilbert analysis. Furthermore, the severity of a winding fault is determined through the analysis of the standard deviation of real mean squared values derived from motor currents.
