Claim 2:
3. The electric driven hydraulic fracking system of claim 1, wherein the VFD configuration further comprises: a VFD transformer that is configured to:
apply a phase shift to a plurality of phase changing sinusoidal signals included in the AC voltage signal associated with the electric power at the power generation voltage level that is generated by the power generation system and received by the VFD configuration, and
convert the AC voltage signal associated with the electric power at the power generation voltage level to the VFD voltage signal at the VFD voltage level based on the phase shift of each of the sinusoidal signals included in the AC voltage signal associated with the electric power at the power generation voltage level to mitigate the level of harmonics in the VFD current waveform included in the VFD voltage signal at the VFD voltage level, wherein the isolation of each VFD cell from each other VFD cell enables the VFD transformer to provide the phase shift to the phase changing sinusoidal signals included in the AC voltage signal associated with the electric power at the power generation voltage level.
