Ying Jianping 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).

  • Power supply with feed forward circuit
    Patent number: 6924634
    Abstract: In those conventional arts, a power supply with a voltage holdup circuit generates a peak voltage in output voltage when a switching operation is occurred, and so the quality of the output voltage is decreased and a risk of operating fault in a load apparatus. The present invention employs a feed forward circuit to immediately generate a forward feedback signal when a switching operation is occurred. Hence, the output voltage can be faster corrected to a accurate output voltage and so the peak voltage can be reduced.
    Type: Grant
