Edward Er Deng 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: 12301124
    Abstract: An AC-DC converter includes an AC voltage source, a rectifier, and a rectifier control circuit. The rectifier includes a field effect transistor (FET) having a source, a drain, and a gate. The drain of the FET is coupled to the AC voltage source, and the source is coupled to ground. The rectifier control circuit is coupled to the gate of the FET. The rectifier control circuit is configured to provide a ramp voltage to regulate the FET after the AC voltage source is turned off.
    Type: Grant

  • Patent number: 11283343
    Abstract: A controller for use in a power converter for transferring energy between an input and an output, the controller comprising a second controller to generate a request event and a request signal in response to a feedback signal and a switching window signal, the second controller to transmit the request event during a switching window of the switching window signal. The second controller comprising an extremum locator switching window generator to generate the switching window corresponding with an extremum in the winding signal and a measurement enable circuit to output an enable signal to enable the extremum locator switching window generator to measure a duration of a half cycle to generate the switching window. The measurement enable circuit to enable the extremum locator switching window generator in response to the feedback signal reaching a percentage of a target reference and output a quiet signal to prevent transmitting the request event.
