Patents by Inventor Yonggen LIU

Yonggen LIU 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: 9362829
    Abstract: Hybrid buck converters that incorporate switching converter and auxiliary linear regulators are described. The auxiliary linear regulators are automatically activated during load transients to source or sink large currents to the output to achieve fast transient responses and are automatically deactivated during steady states to maintain high power efficiencies. With the proposed control scheme of automatic loop transition between linear and switching regulation loops, the power management interface design is simplified while the transient response performances are improved without compromising the power efficiencies.
    Type: Grant
