摘要： An LLC power converter comprises a switching stage and a resonant tank, the switching stage configured to switch an input power at a switching frequency to apply a switched power to the resonant tank, and the resonant tank includes a resonant inductor, a resonant capacitor, and a parallel inductance. A transformer has a primary winding connected to the resonant tank and a secondary winding. A synchronous rectifier (SR) switch is configured to selectively switch current from the secondary winding to supply a rectified current to a load. An RC filter includes a filter capacitor and a filter resistor connected across the SR switch, with the filter capacitor defining a filter capacitor voltage thereacross. A rectifier driver is configured to drive the SR switch to a conductive state in response to the filter capacitor voltage being less than a threshold value.

摘要： A wearable eyebrow-irradiating device includes a main irradiation body, a circumferential light-shielding lining and a fastening headband. The main irradiation body, worn on user's head, has at least one lighting component for projecting respective eyebrow-growth stimulating beams onto corresponding eyebrow-growing zones upon when the main irradiation body is fitted onto the head. The circumferential light-shielding lining, mounted fixedly at the main irradiation body by surrounding the lighting component, is to shield the eyebrow-growing zone, so that an eye can be isolated from the neighboring eyebrow-growing zone. The fastening headband, connecting the main irradiation body, is to wear the main irradiation body tightly onto the head, and to elastically deform the circumferential light-shielding lining so as to completely shield the eyebrow-growing zone and thus to prevent the eyebrow-growth stimulating beam from irradiating the eye.

摘要： A flow control apparatus includes a flow control signal generation device for generating a DC control signal based on an audio signal and at least one proportional valve. The flow control signal generation device includes an audio receiving module, a filter rectifier module, a microprocessor and a proportional valve control signal generation module. The filter rectifier module generates at least one DC audio signal by filtering the audio signal provided by the audio receiving module. The microprocessor generates a plurality of period attenuated values based on the DC audio signal. The proportional valve control signal generation module filters the audio signal, attenuates the signal based on the period attenuated values, and then performs filtering and rectification processing to generate the DC control signal, such that the proportional valve may control the opening ratio of the proportional valve based on the DC control signal.

摘要： A hybrid rectifier that works as either a hybrid full bridge or a voltage doubler. Under 220 V AC input condition, the hybrid rectifier operates in full bridge mode, while at 110 V AC input, it operates as voltage doubler rectifier. The hybrid rectifier may be used with a DC-DC converter, such as an LLC resonant converter, in a power supply. With this mode switching, the LLC converter resonant tank design only takes consideration of 220 V AC input case, such that the required operational input voltage range is reduced, and the efficiency of the LLC converter is optimized. Both the size and power loss are reduced by using a single stage structure instead of the conventional two-stage configuration.

摘要： A system for encoding video data calculates a need parameter for an encoder and then adds a predetermined need bias value to the need parameter. The bias value is added without first determining video source complexity. The system then determines whether the input video comprises static video. Thereafter, the need parameter bias value is scaled in response to a determination that the input video includes the static video.

The light emitting device power supply circuit includes: a phase-cut dimming circuit, a rectifier circuit, a transformer circuit, and a control circuit. The transformer circuit includes an auxiliary winding, which is coupled to a primary winding, for generating a bleeder current to keep a conduction current higher than a holding current and prevent the phase-cut dimming circuit from turning OFF when the phase-cut dimming circuit operates in conductive phase. The control circuit includes a waveform analysis circuit, a bleeder current control circuit, and a bleeder current source. The bleeder current source includes a linear regulator or a variable current source. The bleeder current source controls the bleeder current so that the bleeder current is generated in a continuous and non-switching manner within the conductive phase.
