20130241601 | High-side driver circuit - The present invention provides a high-side driver circuit including a power transistor, the first transistor, the second transistor, the second capacitor, the second diode, a start-up circuit. The start-up circuit is coupled between a resistor and the second capacitor to complete a gate driving circuit. And, the aforementioned resistor can either be the gate resistance of the power transistor or an external resistor. The design of start-up circuit enables the functionality of the bootstrap capacitor of being charged to a designate voltage level. Thus, the depletion-mode transistor can be controlled to turn on/off without a floating voltage source or a negative voltage source. | 09-19-2013 |
20130241603 | Current limit circuit apparatus - The present invention provides a current limit circuit apparatus, coupled with the gate of a GaN transistor. The current limit circuit comprises a diode, a first transistor, a second transistor, a first resistor, a second resistor, a third resistor and a fourth resistor. The source and the drain of the first transistor couple with the diode. The source of the second transistor couples with the gate of the first transistor. The source of the first transistor couples with the first transistor. The source of the second transistor couples with the second resistor. The third resistor couples with the fourth resistor and the gate of the first transistor. The first transistor turned off and the gate current is limited. When the current of the gate of the GaN transistor exceeds the predetermined value, the breakdown voltage is increased by limiting the gate current. | 09-19-2013 |

20140167512 | Method and Apparatus for Powering a Set of Direct-Current Consuming Loads - Set of linked together, direct current powered decorative ornaments. A branched power supply cord is provided that powers a plurality of decorative ornaments, each ornament having a direct current consuming load. The supply cord can include an elongate trunk supply line terminating at a base-end in a pronged plug configured for plugged insertion into an alternating current outlet. The pronged plug can be electrically coupled upstream to a switched-mode power supply having an AC-to-DC rectifier and having variable power output capability, the magnitude of which can be determined by the instant load demand thereupon. An operator-actuable switch can be electrically coupled downstream of the switched-mode power supply and can be electrically coupled upstream of a branched distal portion of the trunk supply line that has a plurality of lead-lines. | 06-19-2014 |
20140167514 | Method and Apparatus for Powering a Battery-Operable Device with an External Source of Power - Object having terminals for supplying power to a battery-operable device when the object is inserted into a battery holder, and a transmission line is coupled to the object for supplying power from an external source of power to the terminals of the object. For example, the transmission line is thin and flat so a battery compartment cover can be fully closed over the transmission line, and the transmission line is also coupled to an external electrical connector to receive power from the external source through the external connector. The apparatus can include multiple objects. The transmission line can provide power from the external source to the terminals of only one of the objects, and the other objects can have their terminals shorted together. The multiple objects can be strung together so that they do not become lost or misplaced. | 06-19-2014 |
