关于一段谐波发射标准的疑问
IEC61000-3-26.2 Harmonic current measurement
6.2.1 Test configuration
For equipment not mentioned in Annex C, emission tests shall be conducted with the user's
operation controls or automatic programs set to the mode expected to produce the maximum
total harmonic current (THC) under normal operating conditions. This defines the equipment
set-up during emission tests and not a requirement to measure THC or to conduct searches for
worst-case emissions.
对于国标
GB17625.1
这不就是说，没有在附录C列出的设备，要在最大谐波发射值模式下测试么？为什么又说“not to conduct searches for
worst-case emissions.” “而不是寻找在最恶劣状态下的发射”？ 按EMC测试标准，一般要求在典型工作状态下进行测试，最大总谐波发射模式举个例子比如满功率情况下测试，而最恶略状态那可能已经不是EUT的典型工作状态了。
