Claim 4:
5. The electric driven hydraulic fracking system of claim 3, wherein each VFD cell further comprises:
a plurality of windings with each plurality of windings isolated from each other plurality of windings that is configured to:
receive the AC voltage signal as the input power to the corresponding VFD cell as the first phase of the AC voltage signal, the second phase of the AC voltage signal, and the third phase of the AC voltage signal; and
segment the AC voltage signal received as the input power to the corresponding VFD cell into the plurality of partitions to convert the AC voltage signal to electric power at a VFD cell voltage level for each corresponding VFD cell, wherein the isolation of the plurality of windings from each other plurality of windings enables each corresponding VFD cell to generate the electric power at the VFD cell voltage level after each corresponding plurality of windings segments the AC voltage signal.
