ALEXANDRIA, Va., Sept. 7 -- Xandex, Petaluma, Calif., has been assigned a patent (8,525,503) developed by Steven P. Weir, Petaluma, Calif., for a hybrid rectifier.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A hybrid voltage rectifier enables a switch mode DC-DC power converter to safely power an external dynamic load by way of a substantially lossless conductive coupling between an output filter of the converter and the load. The rectifier is controlled so as to permit net average current through an inductor of the output filter to be approximately equal to, but not less than, zero by permitting very low loss conduction in the first quadrant and, selectively, cycle by cycle, in the third quadrant during load operation. The converter has a first switch, an output filter, a second switch, and a controller. The output filter is conductively coupled with the first switch, and has an inductor in series with the load. The controller sets state conditions of the second switch, such that the inductor operates in a continuous current mode."
The patent application was filed on May 2, 2011 (13/098,703). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8525503.PN.&OS=PN/8525503&RS=PN/8525503
