  • Publication number: 20240305210
    Abstract: A D-mode GaN transistor synchronous rectifier of the present invention includes a power switching module, a peak detection module, and a gate driver module. The peak detection module stores energy when the negative end of the secondary side winding of the power converter is at a high voltage. The power switching module includes a first switch and a D-mode GaN HEMT as a second switch connected in series. The energy is provided to the module gate of the power switching module through the gate driver module to keep the first switch turned on. The gate driver module conducts the module gate and the module source when the positive end of the secondary side winding is at a low voltage, such that a clamp circuit pulls the gate-source voltage of the second switch below threshold and turns it off. The synchronous rectifier replaces conventional diode rectifier, having lower conduction loss and response ringing.

  • Publication number: 20230093515
    Abstract: A synchronous buck converter using a single gate drive control is provided and includes a drive circuit, a p-type gallium nitride (p-GaN) transistor switch module and an inductor. A gallium nitride power transistor is used as an upper side transistor switch, and a PMOS power transistor is used as a lower side transistor switch in the p-GaN transistor switch module. A gate of the upper side transistor switch and a gate of the lower side transistor switch are coupled to each other and receive a switch signal provided by the drive circuit at the same time. By controlling the on and off of the upper side transistor switch and the lower side transistor switch, the problem of simultaneous activation of the upper and lower side transistor switches can be avoided.

  • Patent number: 11387824
    Abstract: A voltage-controlled varied frequency pulse width modulator is provided, including a frequency-regulating voltage output device which receives a determining voltage, decides a resonant frequency according to the determining voltage and outputs an oscillation signal having the resonant frequency. A duty-ratio-regulating voltage output device receives the oscillation signal and a reference signal to determine a duty ratio through an inverting closed loop, so as to adjust the oscillation signal to have the duty ratio. By employing the proposed voltage-controlled modulator circuit with tunable frequency and varied pulse width of the present invention, a modulation signal having the determined resonant frequency and duty ratio is obtained. Moreover, the present invention can be further combined with gate drive waveform trend feedback designs to achieve superior power transmission efficiency of a wireless power transmission system to optimize the inventive effect of the present invention.

  • Publication number: 20120115421
    Abstract: An apparatus and a method for automatically establishing a new wireless link when the original wireless link between the apparatus and a commercially available FM radio receiver is interfered by other signal sources and reception conditions become poor, thereby eliminating the need to manually configure both the target FM radio receiver and the apparatus to a suitable FM frequency. The apparatus receives an audio signal, modulates and transmits the audio signal to the target FM radio receiver over a selected frequency, scans an FM spectrum for an alternative frequency, transmits an Radio Data System compatible command and a forcible switching signal to configure the target FM radio receiver to tune to the alternative frequency when signal quality of the received signal deteriorate sufficiently.
