摘要
介绍一种应用于三相晶闸管整流或逆变电路的数字移相触发电路,该电路以CPLD为核心,产生的触发脉冲稳定性好,可靠性高;同时不需要同步变压器,实现了相序自适应。
A digital phase-shifted trigger circuit is introduced in the paper, which can use for three-phase thyristor rectification and inverter circuit. The circuit works around the programmable logic device, and produces high stabile and dependable trigger pulses. Meanwhile, it needn't the synchronizing transformers and realizes the self-adapting function of phase sequence.
