Claim 6:
7. The electric driven hydraulic fracking system of claim 5, wherein the VFD transformer is further configured to:
apply a phase shift to each of the plurality of partitions of the segmented AC voltage signal by each corresponding plurality of windings as converted into the electric power at the VFD cell voltage level as the partitions are reconnected into the VFD voltage signal at the VFD voltage level with the decrease in harmonics included in the VFD waveform of the VFD voltage signal at the VFD voltage level due to the isolation of each VFD cell from each other VFD cell.
