摘要
研究了浪涌保护器 (SPD)或电子设备电磁兼容(EMC)试验用组合波发生器 (CWG) ,按IEC和GB要求设计了不同波形参数的CWG。先计算不同虚拟阻抗Z(2、8、12、4 2Ω等 )的回路参数并仿真电路 ;再采用同轴管式分流器和无感分压器测量输出电流和电压波形 ,测量和仿真波形的对比证明理论计算正确 。
The CWG (combination wave generator), which are used for SPD (surge protective devices) charging test, are studied in this paper. The generators meet the requirement of IEC and related Chinese national standards. Firstly, different virtual impedances (i.e.2,8,12 and 48Ω) combination wave generators with different virtual impedances (i.e.2,8,12 and 48Ω) are designed and simulated. secondly, output voltage and current waves are tested through the no-inductance voltage sensor and axial tube current sensor, and contrasting the test waves and simulating wave, it is verified that the theoretical calculations are correct.
