older classical converters are still used at the higher end of the power rating range of these applications. Harmonics CCV operation creates current and voltage harmonics on the CCV's input and output. AC line harmonics are created on CCV's input accordance to the equation, , where = harmonic frequency imposed on the AC line and = integers = pulse number (6, 12 . . .) = output frequency of the CCV Equation's 1st term represents the pulse number converter harmonic components starting with six-pulse configuration Equation's 2nd term denotes the converter's sideband characteristic frequencies including associated interharmonics and subharmonics.
