摘　　要：分析了无环流交交变频器的零电流检测电路中限流电阻取值困难的问题,提出一种以恒流二极管代替限流电阻的解决方案,通过一个典型数据为例,计算了使用恒流二极管的零电流检测电路的基本性能,结果证明使用恒流二极管代替限流电阻可以获得提高检测精度并降低检测电路的功率消耗。In the non-circulating-current cycloconverter, it is difficult to choose the resistance of the current limiting resistor of the zero-current detector, this paper proposes a solution m wmcn tne current .tautog resistor is replaced by a constant current diode. With typical data, the basic performance of the zero-current detector with a constant current diode is calculated. The results show that the detecting accuracy can be raised and the power dissipation can be reduced by using a constant current diode to replace the current limiting resistor.
