PROBLEM TO BE SOLVED: To render a transformer with PCB adhering thereto harmless in safety by a method wherein a transformer with the PCB adhering thereto dried is disassembled, a transformer core is cut to be separated into a copper coil and an iron core and the copper coil and combustible...
A non-contact battery charger using the PCB transformer includes a converter for converting a supply voltage into a high frequency square wave and then applying the converted square wave into a first winding of the PCB transformer; and a charger for converting an electromotive force to a DC ...
PURPOSE: A contactless electric power charging station with PT(Power Transformer)-PCB core of a planar spiral core structure is provided to improve power transmission efficiency by forming a primary core comprised of a plurality of PT-PCB cores. CONSTITUTION: A contactless electric power charging ...
In the mid-1970s, EPA found Lake Hartwell to be contaminated by a single point source, a transformer refurbishing plant located in Pickens, South Carolina (USA). PCB concentrations in the sediments range from 5 to 150 mg/kg (wet basis) (Polansky, 1984, Dunnivant, 1988, Germann, 1988)....
