Harmonics Analysis of Input Current of 3-Phase PWM Rectifier [PDF]
Rectifier is a non-linier load that causes harmonic distortion in the power system. Pulse-width modulation (PWM) method is an effective method in pressing the magnitude of harmonics in a rectifier application, it provides an almost sinusoidal input ...
