What is Total Harmonic Distortion in rectifiers?
The harmonics produced by the rectifier is to be evaluated. TOTAL HARMONIC DISTORTION (THD) : The total harmonic distortion, or THD, of a signal is a measurement of the harmonic distortion present and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency.
What is meant by total harmonic distortion THD?
Total Harmonic Distortion (THD) is a measure of signal distortion which assesses the energy that occurs on harmonics of the original signal. It is specified as a percentage of the signal amplitude.
What is meant by distortion factor for rectifier circuit?
Distortion factor (DF): It is the ratio of the fundamental component to r.m.s value of the waveform. D F = ( V 01 V o r )
What is a good THD percentage?
Measuring THD
For best results, the voltage THD should not exceed 5%, and the current THD should not exceed 20% of the fundamental frequency.
