以晶闸管构成的全桥整流电路为对象,分析和建立了两种触发器以实现对晶闸管的触发控制。一种是以TCA785为核心芯片的模拟触发器,另一种是以可编程逻辑阵列(FPGA)为核心芯片的数字触发器。试验表明两种触发器都具有良好的性能,并且由模拟触发向数字触发的方向发展。
The design research of full-bridge trigger set is made in the paper,including two kinds of chips:TCA785 and FPGA.By means of the experiment results, it can be seen that the digital trigger technology is the main development trend in the future.
