摘　　要：本文提出并介绍了欧姆逻辑无环流检测的一种方案——晶闸管整流器全关断检测,并与软件检测和电流互感器检测进行比较分析,最终得出晶闸管全关断检测方案准确可行的结论。全关断的输出信号与上述两种信号进行综合利用,从而准确可靠地实现了欧姆的逻辑无环流控制。A new method of detecting whether the possive comverter of the HL-2A Ohmic heating power supply is closed thoroughly has been presented in this paper.It is based on detecting the voltages over all the arms of that converter.comparing with methods of current detections by means of software and current transformer,this one is safe and doable.With synthesizing all the signals from the three detectors,the OH power supply system works successfully in without circulating current mode.
