High-power Pulsed Power Supply Automatic Control System Architecture Design

The aim of the thesis is to design a Pulsed-power supply's automatic control system's architecture according to the composing of Pulsed-power supply and the systematical mission's requirement surveying of control system by studying the feature of the Pulsed-power supply's charging and discharging.The supply control system's architecture designed in the thesis make up by charge control subsystem, discharge control subsystem and security control subsystem. PLC as the kernel component to control charging is used in charge control subsystem. The fiber is used for signal transmission, program control time sequence discharge is used in discharge control subsystem's architecture. And the TVS switch is activated by activate generator to realize the function of the discharge from capacitor module to the load. The centralized control of remote computer control mode is adopted by the system to control the charge system and discharge system through fiber transmission. The master computer can do the charge voltage preset, charge control, charge stop, machine close on all the module respectively or simultaneity, and can control the experiment timely and safely also.The soft and hardware form of the automatic control system's architecture are designed also in the thesis according to the control request of the Pulsed-power supply. Charge control, discharge control, safety control, three module are designed in Software Control for requirements of the control system. Safety control system is designed for the feature of Pulsed-power supply.Through the work, Pulsed-power supply's automatic control system's architecture is built initially, computer control Pulsed-power supply's automatic control system's architecture is realized, communication performance of the system is improved, extension ability of the hardware is enhanced and remote control is realized also.The fence of the electromagnetic interference and the research and design of the security protection technology are also discussed preliminarily in the thesis.
