Frequencies of current harmonics 1 phase diode bridge rectifier
Impulses (the current surges) will correlate with ANY time_function.
Correlation is what the maths of Fourier Analysis and Fourier Transform use.
If you use LONG SERIES OF TIME SAMPLES, then the stored_energy reduces the correlation efficiency with arbitrary time_functions, and repetitive time_functions have stronger correlation, and we chose to declare &quot;AHHH Harmonics are present&quot;.
The fast edges of the rectified current surges (low microseconds of turnon time, unless you insert resistors or inductors) will correlate with any time_function. And the repetitive nature of the 60Hz pulses are best (mathematically) correlated with repetitive waveforms.
The imbalanced nature of the current surges will correlate with both even and odd &quot;harmonics&quot;.
