Abstract: A three-phase boost-buck PFC converter including three independent single-phase boost-buck PFC circuits respectively is provided, which are capable of performing PFC on each phase of the three-phase power. The single-phase boost-buck PFC circuit is composed of two single-phase boost-buck converters independently working in a positive and a negative half cycle of an input voltage, and the two single-phase boost-buck converters are connected in parallel at an input side, and are connected in series at an output side, and each of the single-phase boost-buck converters is composed of a front-end boost circuit and a back-end buck circuit connected in cascade. Compared to the existing technique, regardless of a boost mode or a buck mode, the conduction loss is effectively reduced, and the whole system efficiency is effectively improved.

Abstract: A driving apparatus is provided and configured to suit driving at least a string of light emitting diodes (LEDs). The driving apparatus includes a flyback power factor correction (PFC) converter, a harmonics-filtering unit and a control unit. The flyback PFC converter works in an operation mode according to a pulse-width modulation (PWM) signal and receives an AC power so as to convert the AC power into a pulsating current. The harmonics-filtering unit is coupled to the flyback PFC converter and the string of LEDs, for receiving the pulsating current and filtering out the high-frequency harmonic components in the pulsating current so as to drive the string of LEDs. The control unit is coupled to the flyback PFC converter and the harmonics-filtering unit, for producing the PWM signal according to the AC power and the pulsating current, and reducing the peak-to-average ratio (PAR) of the pulsating current.

Abstract: Display ground plane structures may contain slits. Image pixel electrodes in the display may be arranged in rows and columns. Image pixels in the display may be controlled using gate lines that are associated with the rows and data lines that are associated with the columns. An electric field may be produced by each image pixel electrode that extends through a liquid crystal layer to an associated portion of the ground plane. The slits in the ground plane may have a slit width. Data lines may be located sufficiently below the ground plane and sufficiently out of alignment with the slits to minimize crosstalk from parasitic electric fields. A three-column inversion scheme may be used when driving data line signals into the display, so that pairs of pixels that straddle the slits are each driven with a common polarity. Gate line scanning patterns may be used that enhance display uniformity.

Abstract: A power converter topology operates as a switching capacitor (capacitive voltage divider) converter during a first, preferably short portion of a switching cycle to provide excellent dynamic transient response and as a pulse width modulated converter during a second portion of a switching cycle to provide flexibility of voltage regulation and generality of application. This topology can be made self-driven and is capable of zero voltage switching. Therefore the power converter can be used as one of a plurality of branches of a multi-phase converter to enhance transient response. The respective branches can also be independently optimized for particular load levels and can be operated independently in a phase shedding manner to improve efficiency at low load. Further, the power converter or respective branches of a multi-phase power converter are compatible with non-linear control to further improve dynamic response.

Abstract: Methods and apparatus, including computer program products, for identifying a language corresponding to a string of data include receiving a data string and dividing the data string into coded character sequences for each of a plurality of languages. A length of one or more coded character sequences varies among different languages for coded character sequences having a particular number of characters. The coded character sequences are analyzed to calculate, for each of the plurality of languages, a probability that the data string corresponds to language. The calculated probabilities are compared among the languages, and a language is identified as corresponding to the data string based on the comparison.
