Maurice Moroney 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).

  • Short-circuit protection of power semiconductor device by sensing current injection from drain to gate
    Patent number: 11233504
    Abstract: Systems and methods for early-onset electrical fault detection are described in which a rate-of-rise of channel current in a device such as a transistor is sensed, indicating whether an electrical fault is present. In some embodiments, the rate-of-rise of the channel current may be sensed by detecting whether a current flowing away from a control terminal of the device is greater than a threshold level. In the event that an electrical fault is detected, the device may be shut off to prevent damage to the device.
