Claim 19:
20. The electric driven hydraulic fracking system of claim of claim 19, wherein each VFD configuration is further configured to:
reconnect the plurality of partitions of the segmented AC voltage signal by the corresponding plurality of windings as converted into the electric power at the VFD cell voltage level and generated by each corresponding VFD cell into the VFD voltage signal at the VFD voltage level for each corresponding VFD configuration; and
drive each corresponding electric motor from the plurality of electric motors to control the operation of each corresponding electric motor and each corresponding hydraulic pump from the plurality of hydraulic pumps with the VFD voltage signal at the VFD voltage level as reconnected due to the isolation of each VFD cell from each other VFD cell with the decrease in harmonics included in the VFD current waveform of the VFD voltage signal at the VFD voltage level for each corresponding VFD configuration.
