随着现代电子设备的广泛应用,电磁兼容性问题越来越受到关注。电磁兼容性是指电子设备在电磁环境中的正常工作能力,包括电磁辐射和电磁感受性两个方面。其中,电磁辐射是指设备产生的电磁波对周围环境的影响,而电磁感受性则是指设备对周围电磁环境的敏感程度。

低压电源系统中的电压波动和闪烁是电磁兼容性中的一个重要问题。电压波动是指电源系统中电压的瞬时变化,而闪烁则是指电源系统中电压的周期性变化。这些变化可能会对设备的正常工作造成影响,甚至导致设备故障。

IEC TS 61000-3-5:2009/COR1:2009 标准规定了低压电源系统中额定电流大于75A的设备的电压波动和闪烁的限制。该标准要求在设备的额定电流下进行测量,并规定了测量方法、限制值和评估方法。其中,电压波动的限制值为10%(Pst)和1%(Plt),而闪烁的限制值为0.65(Pst)和0.1(Plt)。

该标准的实施可以有效保障设备在电源系统中的正常工作。同时,该标准也为电子设备的设计和制造提供了参考依据,以确保设备在电磁环境中的兼容性。
