当加上非线性负载如调速电动机驱动器时，会影响正弦电源。电压波形畸变变成非正弦波。
When nonlinear loads, such as adjustable speed motor drives, affect a sinusoidal power source, the voltage waveform is distorted and becomes nonsinusoidal.
虽然效率可以提高，当正弦波通过非线形载荷，正弦波失真出现，然后谐波电流通过负载。
Though the efficiency can be enhanced when sine wave passes through non-linear loads, the sine wave distortion appears, and then harmonic current passes through loads.
