Patents by Inventor Kong Soon Ng

Kong Soon Ng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9742276
    Abstract: The present invention discloses a voltage control method. At first, the load voltage of the load is divided to generate a feedback voltage. The feedback voltage and a triangular wave of a triangular wave periodic signal, including the positive voltage and negative voltage, are combined to generate a sum signal. The sum signal is compared with a target voltage, and when the sum signal is less than the target voltage signal, a control signal is generated to control the switches to turn on or off. Finally, the switch receives the control signal and accordingly providing an input voltage to update and stabilize the load voltage.
    Type: Grant

  • Patent number: 9577518
    Abstract: The present invention discloses a voltage control method. First, the load voltage of the load is divided to generate a feedback voltage. Then, an absolute value of a periodic triangular wave signal is retrieved to generate a positive feedback signal, which and the feedback voltage are then combined to produce a sum signal. The sum signal is then compared with a target voltage and when the sum signal is less than the target voltage, a control signal is generated and thus the load voltage is updated and stabilized using an input voltage. In an alternative method, the feedback voltage and the periodic triangular wave signal are combined to generate a sum signal, which is compared with the target voltage. When sum signal is less than the target voltage, a control signal is generated and thus the load voltage is for updated and stabilized using an input voltage.
