An improved energy efficient intelligent pulser driver used for generating a mud pulse in a MWD (measurement while drilling) application. In the pulser driver, a direct current (DC) powered control circuit activates a three-phase DC brushless reversible rotary electric motor that operates a servo-valve, opening of which causes the operation of a main valve to reduce flow area and cause a pressure spike in the mud column. Closing the servo--valve similarly operates the main valve and increases the flow area causing an end to the pressure spike. The servo-valve is powered both in opening and closing operations by a reversible rotary electric motor, which in combination with the mechanical advantage provided by a ball-screw and threaded rod in a rotary-to-linear motion converter, provides sufficient force to overcome the resistance of the type of dynamic seal required for isolating the actuator's drive components from the ambient mud.
