计了一款用于可控硅控制的三相移相触发电路。针对点电网及现场出现的噪声干扰问题，提出了一种去抖动电路设计方案，阐述了移相电路的基本设计思路。通过仿真和实际测试，该触发器的移相范围达到0°~178°，移相精度为0.35°/mV。
Abstract:
This paper designs a phase-shift circuit used to control SCR.Aiming at the problem of noise interference in site, a circuit to get rid of the noise from power system is provided in this paper,and the principle of phase-shift circuit is introduced. The simulaTIon and test results showe that the shift range is from 0° to 178°and the shift resoluTIon is 0.35°/mV.
