关于波形畸变限制的规定符合国家标准GB12668-90“交流电动机半导体变频调速装置总技术条件”，电压的稳态相对谐波含量的均方根值不超过10%。其中任何奇次谐波均不超过5%，任何偶次谐波均不超过2%，短时（持续时间小于30秒）出现的任意一次谐波含量不超过10%。

翻译如下:

Restrictions on the provisions of waveform distortion in line with the national standard GB12668-90 "AC motor VVVF semiconductor devices total technical conditions", the relative steady-state voltage RMS harmonic content does not exceed 10%. Any odd harmonic is less than 5%, any even-order harmonic is less than 2%, short-term (less than 30 seconds duration) of an arbitrary harmonic content of no more than 10%.
