摘要
设计了一种基于可编程系统器件PSD501的触发脉冲产生电路，充分利用PSD501内部的定时器/ 计数器以及PLD逻辑单元来产生三相整流电路所需的六路双窄触发脉冲。该电路硬件电路简单可靠，设计灵活，可通过简单修改内部逻辑实现小型励磁系统单相整流电路所需的触发脉冲序列。本电路已在工程实际中得到成功应用。
Trig pulse generating circuit is an important part in excitation equipment. Its reliability may affect the safe running of generator and power system. This paper describes a trig pulse generating circuit based on Programmable System Device PSD501. In this design, the six two narrow trig pulse for 3 phase rectifier bridge converter can be generated when using the inner Timer/Counter and PLDs of PSD501. The characteristic of this circuit is simple in hardware and agility in software design. It can be used to generate the trig pulse serials for single phase converter while modifing the inner soft logic design and without changing the hardware. This design has been applied in practical excitation equipment successfully.
