基于LABVIEW 的泄漏电流人体阻抗计算模型刘晨,沈介明(工业和信息化部电子第五研究所华东分所,江苏苏州215011)摘要:在测量泄漏电流时,通常使用人体阻抗模拟模型来模拟将通过人体的泄漏电流,泄漏电流的大小是评价电子产品性能的重要指标之一。
计量泄漏电流测试仪时要对人体阻抗模型进行检测,不同的人体阻抗网络对应不同的传输特性。
基于LABVIEW 构建了人体阻抗网络的传输特性计算模型,根据泄漏电流测量的相关标准选取了3个模拟人体阻抗网络模型对传输特性进行计算,从而验证了此计算模型的准确性,提供了一种可以快速地计算不同情况、不同类型的人体阻抗模型参数的方法,对于提高电子产品的安全性具有重要的意义。
