  • Patent number: 8354760
    Abstract: Power supply equipment includes low power assemblies and high power assemblies, each of which is detachably mateable to either one of two power ports. To simultaneously power two low power devices, low power assemblies are respectively mated to each of the power ports. To simultaneously power one low power and one high power device, a low power assembly is mated to one of the power ports and a high power assembly is mated to the other power port. The low power assemblies transfer a low DC voltage, but not a high DC voltage, to low power devices. The high power assemblies transfer a high DC voltage, but not a low DC voltage, to high power devices. If a high power assembly is mated to each of the power ports, power flow is interrupted without putting the power supply in an overvoltage or overcurrent condition.

  • Patent number: 7727005
    Abstract: A key coded power connector and a system and method for making key coded power connections are disclosed. A power connector such as a power adapter connector is configured with either a visual keying system, a physical keying system, or both. The physical keying system prevents a user from connecting a host device to a connector of the power source which does not support that host device. The visual keying system provides the user with an early indication that the particular device is not supported by a power source. The user can visually compare a marking key on the host device with the making key on the power connector and determine whether or not the power source is capable of outputting sufficient power to operate the device. The visual and physical keying systems prevents a user from improperly connecting a host device to a power source which does not support that device.

  • Patent number: 7545656
    Abstract: A common mode noise cancellation circuit eliminates common mode noise generated by a high-frequency switching device. The common mode noise reduction circuit includes a single switching device and a transformer. The switching device receives a rectified voltage and produces a switched voltage. The transformer includes a first primary winding, a second primary winding, and a secondary winding. The transformer couples the switched output from the first and the second primary winding to the secondary winding to generate a transformed voltage. A positive signed common mode noise waveform generated by the switching device is coupled from the first primary winding to the first secondary winding, and a negative signed common mode noise waveform generated by the switching device is coupled from the second primary winding to the first secondary winding, which results in a lower magnitude common mode noise waveform being present at the secondary winding.

    Abstract: A transformer or inductor includes a core, a printed circuit board, a frame and a gapping plate. The core is positioned in a first plane A winding is located on top of a portion of the core. The frame is positioned in a second plane and the frame is located on top of the winding and has a hole. The gapping plate resides in the second plane and is disposed within the hole of the frame. The gapping plate has a smaller area than the hole of the frame and this creates a gap between the gapping plate and the frame.
