  • APPARATUS TO PREDICT FAN WEAR-OUT AND IMPENDING FAILURE AND METHOD OF MANUFACTURING THE SAME
    Publication number: 20100094593
    Abstract: An apparatus for predicting fan wear-out and impending failure and a method of manufacturing the same. One embodiment provides for (1) a lookup table containing expected fan speeds at given duty cycles; and (2) a processor for comparing a measured fan speed at a given duty cycle with an expected fan speed at the given duty cycle, the processor generating a predicted fan wear-out and impending failure.

  • Circuit and method for reducing voltage spikes due to magnetizing current imbalances and power converter employing the same
    Patent number: 7372711
    Abstract: For use in a power converter having parallel power trains, a circuit for, and method of, reducing voltage spikes due to magnetizing current imbalances in the power trains and a power converter incorporating the circuit or the method. In one embodiment, the circuit includes: (1) a conductive bypass path coupling nodes between transformer secondary windings and inductors in each of the power trains and configured to provide an alternative path to redirect magnetizing current imbalances from the inductors and (2) a capacitor located in the conductive bypass path.
