摘要
介绍了基于FPGA的数字移相触发电路,主要应用于三相可控硅整流和逆变电路。该电路以FPGA基础,产生的触发脉冲宽度:TW>1.6ms,脉冲电流峰值:IG>400mA,各相脉冲不均衡度<1°。试验结果表明,该电路产生的触发脉冲稳定性好,相序自适应,抗干扰能力强。
A digital phase-shifted trigger circuit based on FPGA is introduced in this paper, which can be used for three-phase supply power of thyristor rectification and inventer circuit. The width and the peak carrent of pulse that the circuit generated can be over 1.6mS and 400mA, and unequilibrium betweet pulses is less than 1°. The result of experiment showed that trigger pulses are very stable and it has better anti-jamming and great phase sequence self-adapting.
