The Application And Research Of High Voltage Pulse Power

The high-voltage pulse power studied in this article adopted the star-point controller scheme, witch was applied in LHRH system about some controlled nuclear fusion and has the character of high voltage, great current high power strong pulse and so on, there are stated theory meaning and important utility value about the whole research.The article first introduced the compose of high-voltage pulse power supply; and then carried through choice of the power and protection component used in high-voltage valve and thyristor DC power through detailed parameter calculate and capability design; next, we chiefly designed three-phase thyristor controllable DC power, which was abroad applied in high-power Industry-control field, the core control tache- trigger and adjustor is the research hotspot of power electric field. The article researched new type thyristor trigger that adapts the frequency of input power automatically, then analyzed the designing ways and process of frequency-tracked trigger in detail, yet validated capability of trigger through experiment and actual appliance in project, we also build up the fault-diagnosed and disposal cell of hypogyny machine with SIMATIC S7-200 PLC, besides, programmed and debugged to realize various monitor and diagnose; more, smart design make protection function more perfect and action more sensitive, so it can realize perfect swift and reliable protection under fault condition. Finally, we carried through various leave-factory experiment to high-voltage pulse power supply that completed design and manufacture, the result about experiment indicated that the capability of power-supply can entirely achieve technical target.
