Current Characteristics

When main discharge switch is put in discharging course of pulsed power supply in stored energy capacitor branch, the stored energy capacitor may have reverse charging phenomenon. Because of unilateral conductivity of the main discharge switch, the reverse voltage cannot be released and this would adversely affect service life of the stored energy capacitor and reduce working efficiency of the pulsed power supply. Through detailed deducing the discharging course of stored energy capacitor in pulsed power supply system, this paper analyzed relative factors affecting reverse charging voltage of stored energy capacitor and discussed necessary means that could reduce reverse charging voltage of stored energy capacitor. Based on this, a circuit structure with the main discharge switch in load branch is proposed and release of reverse charging voltage of stored energy capacitor is realized without affecting discharge current characteristics of the load. Simulation and test results show that the load current characteristics of the pulsed power supply after adjusting location of the discharge switch is basically the same as before the adjustment is made and completely meet requirement of electromagnetic emission. As a result, timely release of the reverse voltage extended working life of the stored energy capacitor and also improved efficiency of the electromagnetic emission system.

This paper discusses a lithium battery-driven cold plasma jet at atmospheric pressure with a pulsed power supply of design and its simulation. H.V. DC(High voltage directed current) and pulsed discharge circuit comprise of the entire pulse power system. H.V. DC circuit using TIs TMS320F28335 chips as the core of the circuit control module, the chip improves the stability of the H.V.DC circuits. Pulsed discharge circuit design plays a crucial impact on the formation of the narrowed pulses. A new double pulsed discharge circuit is designed by the proposed program. As discharge experiment shown finally, the steep narrowed pulse of pulsed power supply can be used to stabilize the output of the pulsed front.

The plasma polymerization replica method and its apparatus have been devised by Tanaka (1-3). We have published several reports on its application: surface replicas of biological and inorganic specimens, replicas of freeze-fractured tissues and metal-extraction replicas with immunocytochemical markers.The apparatus for plasma polymerization consists of a high voltage power supply, a vacuum chamber containing a hydrocarbon gas (naphthalene, methane, ethylene), and electrodes of an anode disk and a cathode of the specimen base. The surface replication by plasma polymerization in negative glow phase on the cathode was carried out by gassing at 0.05-0.1 Torr and glow discharging at 1.5-3 kV D.C. Ionized hydrocarbon molecules diffused into complex surface configurations and deposited as a three-dimensionally polymerized film of 1050 nm in thickness.The resulting film on the complex surface had uniform thickness and showed no granular texture. Since the film was chemically inert, resistant to heat and mecanically strong, it could be treated with almost any organic or inorganic solvents.

The role of the power supply device is to produce, process and distribute energy sources. Telecommunication equipment can only operate if it has continuous supply. Therefore, to maintain the continuity of the supply, a UPS (Uninterruptable Power Supply) device system is needed so that the supply to the Essential Load device will remain available so that continuity will be maintained. This research designs and proposes how a series of automatic redundant switch systems on UPS to ensure the availability of power supply for the main equipment of telecommunications systems. The Auto switch circuit is designed to have 3 (three) working stages which will trigger the relay driver as control circuit, namely the normal working condition of the contactor input K1 is present, the input condition is zero (lost), and the input condition is present. This system can automatically supply power to telecommunications equipment.
