    摘要: A method and apparatus for a diffusion tip for use with a fuel nozzle is described. The diffusion tip has a substantially circular body including an outer surface and an opposite inner surface. The diffusion tip body extends from a discharge end to an inlet end. The diffusion tip includes an inlet surface adjacent to the discharge end and defined within the body. A discharge surface is defined opposite the inlet surface. A plurality of diffusion apertures each extend between the discharge surface and the inlet surface, each aperture is oriented relative to the body to discharge a diffusion flow outward therefrom at an angle γ (gamma) measured in an X-Z plane between a centerline of the aperture and an X-axis extending tangentially to the outer surface, and at an angle θ (theta) measured in a Y-Z plane between the centerline of the aperture and a Y-axis extending radially outward from the centerline.

    摘要: Linearizers can improve the linearity of power amplifiers by canceling or reducing amplitude of non-linearity components, (e.g., IM3, IM5, IM7, IM9, etc.) generated by the power amplifier. The linearizers can obtain samples of signals output by the power amplifier and process the samples to produce a canceling signal that is applied onto or into an output of the power amplifier. The canceling signal is generated such that when applied to the output of the power amplifier, the canceling signal cancels or reduces at least a portion of the non-linearity components produced by the power amplifier. A controller can improve the correction of the non-linearity components by executing one or more tuning algorithms and adjusting settings of the linearizer based on the results of the algorithm(s).

    摘要: A three-phase rectification module, the system thereof and harmonic suppression method are provided. The module includes a LCL filter unit, a three-phase uni-directional rectification unit coupled to the LCL filter unit, and a rectifier control unit for controlling power factor of three-phase AC power source and DC output voltage of the three-phase uni-directional rectification unit. A commutation diode is serially connected on the bridge-arm of each set of uni-directional rectification branch which is included in the three-phase uni-directional rectification unit, making it function as current uni-direction. Herein, the power factor of the three-phase AC power source is matched with the parameters of the LCL filter unit, such that the absolute value of the phase difference between AC input voltage and current of the three-phase uni-directional rectification unit is close or equal to a preset threshold.
