开关模式电源 (SMPS) 是最常见的负载类别之一，通常在现代电源系统中大量存在。这些设备通常消耗非线性电流，因此是重要的谐波源。尽管众所周知，谐波的存在会导致负面影响（例如更高的热应力和过载，或中性导体电流增加），但评估实际谐波水平并不是一项简单的任务。
Switch-mode power supplies (SMPS) are one of the most common category of loads, typically found in large numbers in modern power supply systems. These devices usually draw non-linear current and are, therefore, significant sources of harmonics. Although it is well known that the presence of harmonics will result in negative effects (e.g. higher thermal stresses and overloading, or increased neutral conductor currents), the assessment of the actual harmonic levels is not a simple task.
