说到全球电网电压的差异，或许会让不少人感到陌生。但提到出国旅游总要带转换插头的尴尬，相信大家会更加熟悉。

中国、英国、法国、德国等国家采用220-240VAC标准电压。而美国、加拿大、日本这些国家普遍采用100V-130VAC标准电压，巴西则采用220VAC/110VAC/127VAC混合电压，这就是全球电网的电压差异。

当消费者还在为跨国旅行携带转换插头而困扰时，智能电源细分领域的从业者正面临更严峻的技术命题：如何在复杂的电网环境中实现稳定调光？

While consumers are still troubled by carrying conversion plugs when traveling across borders, practitioners in the smart power segment are facing a more severe technical proposition: how to achieve stable dimming in a complex power grid environment?

因为智能电源内部集成了精密的电子元件和控制芯片，对输入电压的稳定性要求极高。而电网电压差异会引发电压波动，影响电网稳定性，并且产生不同程度的谐波干扰，从而导致调光不顺畅、灯光闪烁等各种问题。

Because the smart power supply integrates sophisticated electronic components and control chips, it has extremely high requirements for the stability of the input voltage. The difference in grid voltage will cause voltage fluctuations, affect grid stability, and generate varying degrees of harmonic interference, resulting in various problems such as uneven dimming and flickering lights.
