摘　　要：在某核电站棒控电源系统产品设备系统联调试验中,整流器带纯电阻性负载,当负载电流增加到额定电流的20%左右时,整流器报"同步故障"并停止输出。出于实际工程项目的时效、成本等多方面考虑,在不改变输入侧容量的基础上,为整流器的同步采样回路设计一个以50 Hz为中心频率的四级二阶带通滤波器。经过理论推导、软件仿真、硬件设计及现场模拟试验,较为有效地实现了在输入侧容量较小的情况下采样回路仍然正常工作的目的。During the equipment-system joint commissioning test of the rod control power supply system product of a nuclear power plant,failure occurred in the rectifier:for the rectifier operated with a pure resistive load,when the load current increased to about 20% of the rated current,the rectifier reported "synchronous fault"and stopped output.Considering the timeliness,cost and other aspects of the actual project,a four-stage second-order band pass filter with 50 Hz center frequency is designed for the synchronous sampling loop of the rectifier without changing the input side capacity.Through theoretical derivation,software simulation,hardware design and field simulation experiment,the purpose of normal operation of the sampling loop is effectively realized when the input side capacity is relatively small.
