  • Publication number: 20090085543
    Abstract: A method of generating at least a first voltage and a second voltage in a power converter including at least one DC-DC converter is disclosed. The method includes operating the DC-DC converter as a full-bridge converter to generate the first voltage and operating the DC-DC converter as a half-bridge converter to generate the second voltage. Power supplies including a DC-DC converter selectively configurable as a full bridge converter to provide a first DC voltage and as a half bridge converter to produce a second DC voltage and controller circuits for such configuration are also disclosed.

  • Publication number: 20090086518
    Abstract: A method of programming a switching mode power supply before or after the power supply is installed in a system to control electromagnetic interference. The switching mode power supply includes at least one switching device and a digital controller. The digital controller adjusts a switching frequency of the at least one switching device based on one or more programmable parameters. The method includes programming the digital controller with the one or more programmable parameters via a user interface. The programmable parameter(s) define a switching frequency adjustment to control electromagnetic interference.

  • Publication number: 20090073731
    Abstract: A method for detecting a performance degradation of a fan in a power converter is disclosed. The method includes monitoring a speed of the fan and detecting the performance degradation of the fan based, at least in part, on the monitored speed. The method further includes generating a warning signal after detecting the performance degradation of the fan. According to another aspect, a power converter includes a fan and a processor operably coupled to the fan for monitoring a speed of the fan. The processor is configured for detecting a performance degradation of the fan based, at least in part, on the monitored fan speed. The processor generates a warning signal after detecting the performance degradation of the fan.

  • Publication number: 20080285192
    Abstract: A power converter includes a controller having at least one input for monitoring a rate of change of an operating parameter of the power converter. The controller is configured for comparing the monitored rate of change of the operating parameter with an allowable rate of change for the operating parameter, and for generating a fault signal when the monitored rate of change of the operating parameter deviates from the allowable rate of change for the operating parameter. The operating parameter for which the rate of change is monitored may be, for example, a temperature, a current and/or a voltage in the power converter.

  • Publication number: 20080285184
    Abstract: A power converter includes a controller and at least one output terminal for providing an output voltage and an output current to a load. The controller is configured for monitoring the output voltage and the output current and calculating an efficiency of the power converter based on the monitored output voltage and output current. The controller is also configured to generate a fault signal after detecting a degradation in the power converter efficiency.

  • Patent number: 6454604
    Abstract: An enclosure for small power supplies for cellular telephones, laptop computers and the like is formed in two layers. The first layer is an inner box constructed of a pair of about 0.8 mm thick PBT shells that enclose and retain the electronics. The second layer is an overmolding of about 1.0 mm. thick PVC that surrounds the shells, seals them together, and forms a strain relief for a cable attached to the electronics. The two-layer construction allows considerable savings in material and assembly costs.
