Abstract:

The HL-2A pulse generators outputs are controlled by their excitation feed back control systems, which adopt PID algorithm and the phase-shifted digital trigger circuit based on FPGA (field programmable gate array), and the safety of the excitation system is protected by Siemens PLC logic control system. The actual operation results show that these excitation control systems have high control precision, stable and reliable advantages.
