In this paper, the impact of three dimensional effect of multi-finger layout on Variation of Lateral Doping (VLD), the Variation of Lateral Thickness (VLT) and Reduced Surface Field (RESURF) LDMOS is explored. These devices are compared on the basis of breakdown voltage and on-state resistance. The simulation indicates that compared with VLT and conventional RESURF LDMOS, the breakdown voltage of...
Recent years the application of ultraviolet-irradiation crosslinked polyethylene (UV-irradiation XLPE) cable for low voltage has become increasingly mature, but for high voltage is still in the research stage. The dielectric properties of high voltage UV-irradiation XLPE with new type macromolecule photoinitiator and polyfunctional crosslinker were studied in this paper. The influence of irradiation...
LDPE has been widely used in electrical insulation and high voltage device application. In this paper we have studied the characteristics of electrical tree aging at AC voltage in LDPE, with the continuous applied voltage to observe the propagation of electrical tree. The electrical tree experiments were carried out with needle-plane specimens. At the same time the barriers of different polymer films...
In the present paper, the dielectric properties of polypropylenes with different crystal forms were investigated. The space charge distribution was measured by using electro-acoustic pulse and the effect of space charge on short circuit breakdown was analyzed by using DC pre-stress voltage. Relative crystallinity of the beta crystal in beta crystal form polypropylenes was analyzed by using DSC, and...
