  • Patent number: 7830269
    Abstract: A method for detecting a performance degradation of a capacitor in a power converter is disclosed. The method includes monitoring a voltage across the capacitor, detecting the performance degradation of the capacitor based on the monitored voltage, and generating a warning signal after detecting the performance degradation of the capacitor. A power converter is including at least one capacitor and a processor operably coupled to the at least one capacitor for monitoring a voltage across the at least one capacitor is also disclosed. The processor is configured for detecting a performance degradation of the capacitor based, at least in part, on the monitored voltage, and for generating a warning signal after detecting the performance degradation of the at least one capacitor.

  • Patent number: 7817051
    Abstract: A power converter including a processor, at least one component whose health in the power converter will degrade over time, and at least one alarm is disclosed. The processor is configured for monitoring the health of the component over time, and for activating the alarm when the monitored health of the component reaches a threshold level.

  • Patent number: 7804415
    Abstract: A power converter including a processor and at least one component whose health in the power converter will degrade over time is disclosed. The processor is configured for monitoring the health of the component over time, and for generating a warning signal when the monitored health of the component reaches a threshold level. A method for monitoring the health of at least one component in a power converter is also disclosed. The method includes monitoring at least one performance characteristic of the power converter. The performance characteristic represents the health of the component. The method further includes comparing the monitored performance characteristic with stored data to determine whether the health of the component has reached a predetermined level, and generating a warning signal after determining the health of the component has reached the predetermined level.
