  • Publication number: 20110095731
    Abstract: A power factor correction controller is utilized for a power factor correction circuit in a critical conduction mode of an electric power converter. The power factor correction controller generates a control voltage according to an output voltage outputted from the electric power converter, and utilizes a first threshold value to detect the control voltage. The power factor correction controller can control the power factor correction circuit to operate in different modes according to various levels of a load. Therefore, an objective according to the present invention for reducing electric power consumption of the electric power converter in a light load or a no-load mode and improving energy transmission efficiency can be attained.

  • Patent number: 7724103
    Abstract: A self-sustaining ultra-high frequency oscillator and method enable the ability to oscillate and output a signal. A balanced bridge circuit is utilized to null an embedding background response. A first vibrating nanoelectromechanical (NEMS) beam resonator is part of one of the branches of the balanced bridge circuit and determines the frequency of the oscillator's output signal. A feedback loop establishes and sets oscillation conditions of the oscillator's signal. Further, the feedback loop connects an output of the first resonator to an input of the balanced bridge circuit.
