This paper has presented the calculation of the switching angles based on the selective harmonic elimination scheme to minimize the total harmonic distortion (THD)of a multilevel flying capacitor inverter (MFCI). Harmonic elimination in multilevel inverters using cuckoos search algorithm 4 November 2016...
So I googled it, and found a simple, yet still unexplained reason: wiki on the farad said: The millifarad is less used in practice, so that a capacitance of 4.7×10−3 F, for example, is sometimes written as 4700 µF; industrial parts at times use the abbreviation MFD. North...
