Pulse power systems have been stimulated intense interest towards high power, compact structure and high reliability. In this paper, a compact megavolt pulse autotransformer with inner cylindrical magnetic core and conical secondary windings is presented. First, the operation principal and the geometrical structure are described. At the same time, the electric c ircuit is analyzed and the parametric...
In this paper, 5Xnm cross point cell array for the low power ReRAM operation was developed with 1S1R cell structure. Through the optimization of both TiOx/TaOx based-1R and NbO2 based-1S stacks with TiN based-electrode, the world's first and best bipolar switching characteristics with the lowest operation current (20∼50uA) and sneak current (∼1uA) level were acquired.
Compared to permanent magnet synchronous generator (PMSG), cage induction generator (CIG) has some advantages in off-grid micro hydro generation, because of its unique characters, such as economical, durable, and etc [1]. CIG can not provide excitation by itself and it is too weak to support heavy load. This article mainly describes a method to provide stepping variable excitation by a capacitor bank...
Deionized water is a good dielectric material. In this paper, preliminary investigations are carried out on water breakdown in tens nanoseconds region via a switch with “point-plane” electrodes. The switch is set up on the output port of a wave erection Marx generator, which can deliver a minus high voltage pulse with an amplitude of 0∼300 kV, and a pulse width of 40∼50 ns to a matched load. According...
