摘　　要：可控硅触发脉冲产生电路适用于单相、三相全控桥式供电装置中。一般可控硅移相触发电路采用硬件实现。本文中利用FPGA芯片由VHDL语言编程实现,可以更准确、简便地产生可控硅移相触发所需的双窄脉冲。与硬件电路实现相比,FPGA(现场可编程门阵列)的实现不但能有效防止由于可控硅换流而引起的误控制,而且集成度高,更精确和灵活。Thyristor trigger pulse is suitable to be used in single-phase or three-phase fun-control-bridge power supply device. The trigger pulse is usually generated by hardware. This paper introduced a new way which used VHDL programming language in FPGA chip. This way is more accurate, convenient and flexible. In compared with the hardware realization, this way can not only avoid false control caused by the phase-change of thyristor effectively, but also have high integration.
