摘　　要：为解决普通三相全控整流桥脉冲移相电路的不足,采用单片机及数字移相技术,自行设计和制造出大功率的数字式脉冲移相电路,应用于大中型发电机组励磁装置中。文章给出了数字式脉冲移相电路的硬件组成和软件设计。实际应用证明,该数字触发电路性能优越、稳定可靠,能够更好地满足大中型发电机组励磁设备的技术要求。A high-power digital pulse phase-shift circuit is designed and produced in order to solve the shortage of pulse phase-shift circuit of general three-phase full-control rectifier bridge. The digital pulse phase-shift circuit is adopted single chip and digital phase-shift technology. It can be applied to large and medium-size generator set excitation equipment. Its hardware components and software design are discussed. The actual application shows that the circuits own high performance and well stabilization and reliability and satisfies the technology demands of large and medium-size generator set excitation equipment.
