1. An electric driven hydraulic fracking system that pumps a fracking media into a fracking well to execute a fracking operation to extract a fluid from the fracking well, comprising:
a Variable Frequency Drive (VFD) configuration includes a plurality of VFD cells with each VFD cell isolated from each other VFD cell that is configured to:
segment an AC voltage signal that is associated with electric power generated at a power generation voltage level by a power generation system into a plurality of partitions to convert the AC voltage signal associated with the electric power at the power generation voltage level to a VFD voltage signal at a VFD voltage level based on the isolation of each VFD cell, wherein the VFD voltage level is a voltage level of that is required to drive an electric motor to control a hydraulic pump, and
reconnect each partition into a configuration that generates the VFD voltage signal at the VFD voltage level based on the isolation of each VFD cell to drive the electric motor to control an operation of the electric motor and the hydraulic pump with a decrease in a level of harmonics included in a VFD current waveform of the VFD voltage signal at the VFD voltage level.
