A SEPIC converter powered off line is controlled to improve the input power factor by forcing the current in the input inductor (205) to assume the same wave shape as the voltage across the inductor, which is in series with the power switch (207), to insure a sinewave input current. A...
However, the conversion of radial to pulsational velocities in the PoP method relies on a poorly calibrated parameter, the projection factor (p-factor)... J Breitfelder,A Mérand,P Kervella,... - 《Astronomy & Astrophysics》 被引量: 0发表: 2016年 Real-time PCR primers and probes for...
(3.80) years for monkeys ranging from 15–28 years; Supplementary Table1). The putative human equivalent using a 1:3 conversion is 65.33 (11.39) years, ranging 45–84 years. Monkeys were maintained in accordance with the Yale University Institutional Animal Care and Use Committee and federal...
A three-phase single-stage full-bridge power factor correction converter is presented in this paper. The converter could achieve power factor correction and AC/DC power conversion in one stage circuit. It could achieve electrical isolation between input and output sides. The voltage stress of each...

A power factor correction converter and a power factor correction conversion device, includes two groups of bidirectional switches, an autotransformer, a boost inductor, a bus filter capacitor, two front bridge arms; and a rear bridge ar... D Pan 被引量: 1发表: 2013年 Automatic Power Factor ...
A flyback-based single-stage power-factor-correction scheme with time-multiplexing control (TMC) is proposed. As a portion of the input power will be transferred to the output after the first power processing to improve the conversion efficiency, the output voltage would contain substantial low-fr...
Microbial conversion occurs chiefly at or near the soil surface, where bacterial populations and organic carbon levels are high. Low organic carbon levels limit microbial action in the deeper regions of the vadose zone during treatment in rapid-infiltration systems. The travel time of an organic ...
