Abstract: The development and application of the PSVR100 excitation regulator were introduced. In the PSVR100 regulator, the 32 bits dual core processor MPC8247 and the field programmable gate array (FPGA) are adopted to constitute the hardware framework which can satisfy the requirements of excitation control in high computation speed and high reliability of the regulator; the embedded realtime operation system VxWorks was introduced which can ensure the instantaneity of the excitation control, simplify the development process of the excitation application software and increase the software transportability; the graphical programming method was adopted which can provide certain convenience for software modification during engineering application process; the channel redundance, the sample redundance, the multiple realtime selfchecking and other technologies were adopted to enhance the reliability of the excitation regulator. The successful application of the regulator in selfshunt excitation system and threemachine excitation system (the threemachine brushless system is included.) shows that PSVR100 excitation regulator has excellent control indicators and higher reliability.
