Patents by Inventor Dalun Yuan

Dalun Yuan 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).

  • Publication number: 20120051110
    Abstract: Embodiments of the invention relate generally to semiconductors for power generation and conversion applications, and more particularly, to devices, integrated circuits, substrates, and methods to convert direct current (“DC”) voltage signals to alternating current (“AC”) voltage signals. In some embodiments, a method for converting DC voltage signals to AC voltage signals can include generating a first portion of an output voltage signal using a polarity circuit, generating a second portion of the output voltage signal using another polarity circuit, wherein the output voltage signal comprises an AC signal, and synchronizing the first portion and the second portion of the output voltage signal to a frequency using an AC reference signal.

  • Patent number: 8009449
    Abstract: Embodiments of the invention relate generally to semiconductors for power generation and conversion applications, and more particularly, to devices, integrated circuits, substrates, and methods to convert direct current (“DC”) voltage signals to alternating current (“AC”) voltage signals. In some embodiments, an inverter can include a modulator configured to convert a direct current signal into a first variable signal, and a transformation module configured to step up the first variable signal to form a second variable signal. The transformation module can be configured to generate a first portion of the second variable signal and a second portion of the second variable signal. Further, the inverter can include a waveform generator configured to synchronize the first portion and the second portion of the second variable signal at a frequency to generate an alternating current (“AC”) signal.
