9793 results about "Charge control" patented technology

Charge control is a technology that lets an electric utility control, in real time, the charging of a gridable (plug-in) vehicle, such as a plug-in hybrid (PHEV) or a battery electric vehicle (BEV). Through charge control, the utility is able to postpone charging of the vehicle during time of peak demand. Additionally, this technology may enable the owner and the power company to track the vehicle's usage and performance, while on the road and while charging.

Method and apparatus improving gate oxide reliability by controlling accumulated charge

ActiveUS20070069291A1Improving nonlinear responses and harmonic and intermodulaton distortion effectsReduce non-linearitySolid-state devicesElectronic switchingMOSFETDielectric
A method and apparatus are disclosed for use in improving the gate oxide reliability of semiconductor-on-insulator (SOI) metal-oxide-silicon field effect transistor (MOSFET) devices using accumulated charge control (ACC) techniques. The method and apparatus are adapted to remove, reduce, or otherwise control accumulated charge in SOI MOSFETs, thereby yielding improvements in FET performance characteristics. In one embodiment, a circuit comprises a MOSFET, operating in an accumulated charge regime, and means for controlling the accumulated charge, operatively coupled to the SOI MOSFET. A first determination is made of the effects of an uncontrolled accumulated charge on time dependent dielectric breakdown (TDDB) of the gate oxide of the SOI MOSFET. A second determination is made of the effects of a controlled accumulated charge on TDDB of the gate oxide of the SOI MOSFET. The SOI MOSFET is adapted to have a selected average time-to-breakdown, responsive to the first and second determinations, and the circuit is operated using techniques for accumulated charge control operatively coupled to the SOI MOSFET. In one embodiment, the accumulated charge control techniques include using an accumulated charge sink operatively coupled to the SOI MOSFET body.
