Abstract
A system for and method of use with a downhole tool that includes a tubular with a fluid flow path therethrough for flowing a fluid and a housing coupleable to a downhole portion of the tubular. A fluid-driven motor assembly is included and has a drive shaft rotatable to output rotational drive forces. An electric generator is coupled to the drive shaft to convert the rotational drive forces into electrical power. There is also an electric motor electrically coupled to the electric generator to convert electrical output of the electric generator into a rotational drive force to control the downhole tool. A controller is electrically coupled to the electric motor and the electric generator to conduct electrical power output from the electric motor to the electric generator and dissipate excess energy produced by the electric motor to the fluid-driven motor assembly as hydraulic energy.
