Claim 15:
16. The electric driven hydraulic fracking system of claim 15, wherein each VFD configuration is further configured to:
mitigate the level of harmonics in the VFD current waveform included in the VFD voltage signal at the VFD voltage level, wherein the VFD voltage signal is converted from the AC voltage signal generated by the power generation system; and
drive the corresponding electric motor from the plurality of electric motors to control the operation of each corresponding electric motor and the corresponding hydraulic pump from the plurality of hydraulic pumps with the mitigated level of harmonics included in the VFD current waveform of the electric power at the VFD voltage level.
