Description
Summary:On occasions where the inductance of high voltage coils must be raised by utilizing ferromagnetic cores, it has been found that partial cores comprised of symmetrical arrangements of ferrite bars are more efficient in terms of inductance gain per weight of material than either full-flux path cores or solid-slug type cores. Proper placement of the core material, however, is essential to achieving maximum inductance gain. This paper will describe a series of experiments that were conducted to determine the optimum arrangement of distributed bar-type partial cores. Data from the various experiments will be presented.
