摘要： The present invention refers to a method for controlling a resonance DC/DC converter, which adjusts an output voltage by changing a turn-on frequency of input switch devices of a resonance circuit of the converter, and extends the range of the output voltage of the resonance circuit by adjusting the duty ratio of the switch devices based on the feedback signal of the load circuit. The present invention also provides the resonance DC/DC converter structure using the controlling method. The advantage of the present invention lies in the use of two modes of frequency modulation and frequency modulation plus pulse width modulation to control the resonance DC/DC converter; the use of the frequency modulation controlling mode when the operating frequency of the power supply is low, and introducing the frequency modulation plus pulse width modulation controlling mode when the operating frequency of the power supply is too high. As a result, the problem of the resonance converter, that is, the high operating frequency and the big loss of the circuit when the circuit operates at a light load and non-load, can be solved, and thus the regulation ability for the output voltage of the resonance circuit is enormously improved, and the output range of the voltage is effectively expanded.

摘要： A method and system for realizing network switching, and a mobile node are provided. An LMA receives a PBU message from a second MAG, wherein the PBU message carries identifier information of the mobile node, the IP address of a first interface, and the IP address of the second MAG. The LMA checks in the stored BCE whether the identifier information of the mobile node and the IP address of the first interface exist. If the existence is checked, the LMA continually judges whether the Proxy Care-of-Address in the BCE is the same as the Proxy Care-of-Address in the PBU message. If they are different, the LMA determines that the connection of the mobile node is a switchable connection, and determines that the mobile node has the ability of address preservation, then sends the IP address of the first interface to the second MAG.

摘要： A method and system of radio frequency (RF) power transmission among multiple wireless stations is provided. Control signals for switching a receiving station between a power reception mode and a data reception mode are generated. The control signals provide switching information about which of the modes to switch to, and timing of the switching. In the data reception mode, the receiving station processes an RF transmission from a sending station as a data communication. In the power reception mode the receiving station processes the RF transmission as energy radiation for powering the receiving station. One type of control signal for power mode switching is generated at the MAC layer of a receiving station and sent to the PHY layer of that station for power mode switching. Another type is RTS/CTS control signal exchanged between the sending and receiving stations.
