# How Electric Power Systems Run Industrial Fracturing Equipment > This patent describes an electrical power system for fracturing equipment, using separate high-voltage and low-voltage generators and switches to efficiently power a main motor and its auxiliary devices. - **Patent:** US 12735969 - **Original title:** Electrically-driven fracturing system - **Granted:** 2026 - **Status:** Active - **Times cited:** 0 - **Field:** energy, oil_and_gas, electrical_engineering, power_generation, mechanical ## What it does The patent outlines an electrically-driven fracturing system that uses two distinct power sources. A powerful "main power generation device" supplies high voltage to the main "fracturing motor" through a high-voltage switch group. Separately, a less powerful "first auxiliary power generation device" provides lower voltage to a "fracturing auxiliary device" through a low-voltage switch group. This setup ensures that the heavy-duty motor receives ample power, while other components, like control systems or lighting, are powered appropriately. For example, a large gas turbine might power the main fracturing pump, while a smaller diesel generator or battery system powers the control cabin and fluid handling equipment. ## What it does NOT cover - Does not cover fracturing systems powered solely by traditional internal combustion engines without electrical drive. - Does not cover power systems where a single generator supplies both the main fracturing motor and auxiliary devices without distinct high and low voltage switch groups. - Does not cover systems where the auxiliary power generation device has a rated power or voltage equal to or greater than the main power generation device. - Does not cover the specific mechanical design of the fracturing pump, wellbore tools, or the chemical composition of fracturing fluids. - Does not cover systems where the main power generation device is not connected to the fracturing motor, or the auxiliary device is not connected to the auxiliary power. ## The clever bit The novelty lies in the specialized dual-power architecture: using separate main and auxiliary power generation devices with distinct voltage ratings and switch groups. This allows for optimized, segregated power delivery to the high-demand fracturing motor and its lower-demand auxiliary components, improving efficiency and control. ## Real-world examples 1. Electrically-powered fracking fleets in oil and gas fields 2. Hybrid power systems for industrial pumping operations 3. E-fracking equipment used by major oilfield service companies 4. Modular power generation units for remote industrial sites ## Why it matters Electrically-driven fracturing systems are a key development in the energy industry, aiming to reduce emissions, noise, and fuel costs compared to traditional diesel-powered operations. This patent focuses on a specific electrical architecture that enables efficient power delivery for these complex systems. It addresses a critical aspect of transitioning to more sustainable and cost-effective energy extraction methods. ## Frequently asked questions ### What does How Electric Power Systems Run Industrial Fracturing Equipment cover?
