    摘要: A voltage regulator exhibits a load line that is piecewise linear. This piecewise linearity variation has a first constant voltage segment VLEAK at which output voltage is regulated for output currents less than or equal to the leakage current IL. The output voltage VLEAK corresponds to the maximum output voltage allowable at the leakage current for a given operational range specification. The piecewise linearity variation further includes a second, linearly decreasing segment that varies from the maximum allowable output voltage VLEAK at the leakage current to a full load voltage VDROOP at full load current IFL. This serves to effectively maximize the available output voltage swing in the presence of a leakage current offset. The piecewise linear load line is adjustable to accommodate changes in leakage current.

    摘要: A synthetic ripple regulator including a synthetic ripple voltage generator that generates a synthetic ripple voltage indicative of the ripple current through an output inductor. The regulator uses the synthetically generated ripple voltage to control toggling of a hysteretic comparator for developing the pulse width modulation (PWM) signal that controls switching of the regulator. In a non-limiting implementation, a transconductance amplifier monitors the phase node voltage of the inductor and supplies an inductor voltage-representative current to a ripple capacitor, which produces the synthetic ripple voltage. Using the replicated inductor current for ripple regulation results in low output ripple, input voltage feed forward, and simplified compensation.

    摘要: A purging electrostatic gun for uniformly and essentially completely electrostatically charging the outer surfaces of a flow of sorbent material particles passed therethrough under pressure that are then injected into a polluted gas stream for contacting to electrostatically attract and react to pollutant particles and pollutant gases in that gas stream that are then removed in a conventional pollution control filtration device. The purging electrostatic gun includes a housing wherein a charging electrode is maintained that is electrically coupled to receive a high voltage and is axially centered in a cylindrical barrel charging section wherethrough a laminar flow of sorbent material is directed. The charging electrode has a forward portion that extends beyond a barrel charging section forward end and is immediately opposite to a surface of a grounding ring or collar. The grounding ring or collar is maintained in the housing and is connected to earth ground. A purging air flow is directed into the housing to pass across the barrel charging section outer surface and the grounding ring or collar surface to prohibit sorbent particles from collecting on the grounding ring or collar as could interfere with generation of a corona discharge that extends from the charging electrode end portion radially wherethrough the sorbent material particles travel and are electrostatically charged.
