摘要
对18款不同类型LED灯具的谐波含量进行测量,依据IEC 61000-3-2:2018《Electromagnetic compatibility(EMC)—Part 3-2:Limits—Limits for harmonic current emissions(equipment input current≤16 A per phase)》对灯具总谐波畸变率(THD)限值进行判定。同时对比不同类型LED灯具在调光状态下的谐波含量,并对测量结果进行分析。
This paper measures the harmonic content of 18 various types of LED luminaires,and determines the limit of total harmonic distortion(THD)according to the Electromagnetic Compatibility(EMC)-Part 3-2:Limits-Limits for Harmonic Current Emissions(Equipment Input Current≤16 A per Phase(IEC 61000-3-2:2018).It also compares the harmonic content of various types of LED luminaires under the dimming state,and analyzes the measurement results.
