  • Publication number: 20170117809
    Abstract: A multifunction power conversion device for dynamical detection includes an input filter unit, a transformer, a switching transistor, a driving controller, a feedback unit and an output unit. Two sensing signals from the primary and auxiliary coils of the transformer form a current sensing zero detection signal. The digital control unit of the driving controller determines if a current flowing through a secondary coil of the transformer is reduced to zero due to discharging, and further finds valley of the current of the secondary coil. The switching transistor is turned on after a preset number of the valley and then turned off by a process of current sense. Therefore, the present invention greatly reduces switching loss, increases efficiency of power conversion, and particular, enhances flexibility of application to meet actual requirements by simply updating program executed by the digital control unit.

  • Patent number: 9554322
    Abstract: A transmission control method for a vehicular ad hoc network system having a plurality of mobile nodes is provided. The mobile nodes include a source node, a destination node, and a plurality of relay nodes. The source node transmits a data packet to the destination node through the relay nodes. The method includes each mobile node capturing mobility information being periodically broadcasted from neighboring mobile nodes to correspondingly update the connection state table thereof, wherein the connection state table records the coverage remaining time between the mobile node and neighboring mobile nodes; when any of relay nodes determines that the coverage remaining time between the relay node and the subsequent mobile node is less than a predefined threshold, the relay node transforms into a proxy node, stores the data packet, and establishes a reliable sub-connection between the proxy node and a next proxy node or the destination node.

    Abstract: A power factor correction control device for dynamically sensing and boost regulation includes a rectifying unit, a transformer, a digital regulation controller, a driving element, a sensing resistor, an output diode and an output capacitor. The control device converts an AC input power into a DC output power so as to supply an external load. The transformer includes a primary coil and an auxiliary coil, the controller employs an auxiliary voltage from the auxiliary coil to calculate the current input voltage and the current output voltage to implement feedback control for the driving element. The driving element is thus turned on and off by the controller to achieve boost function such that the output voltage is greater than the input voltage. The present invention obtains the input voltage and the output voltage by calculation without any sensing resistor, thereby reducing power consumption and increasing power conversion efficiency.

The rectifying unit rectifies an AC input power to generate and transfer a DC power to the power factor correction unit for performing power factor correction. A power factor correction power is generated and transferred to the power conversion unit. The feedback unit is electrically connected to the power conversion unit to form a closed control loop. A PWM driving controller of the power conversion unit performs an adjustment process to control a switching transistor based on a feedback signal from the feedback unit, and the power conversion unit converts the power factor correction power into an output power supplied to an external load. Thus, the margin for electromagnetic interference is increased, and both switching loss and conduction loss are considerably reduced.
