Claim 7:
8. A method for 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: segmenting by a Variable Frequency Drive (VFD) configuration an AC voltage signal that is associated with electric power generated at a power generation level by a power generation system into a plurality of partitions to convert the AC voltage signal associated with the electric power generated at the power generation voltage level to a VFD voltage signal at a VFD voltage level based on an isolation of each VFD cell from a plurality of VFD cells included in the VFD configuration, wherein the VFD voltage level is a voltage level 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 waveform of the VFD voltage signal at the VFD voltage level.
