Variable speed drive with hydraulic boost
International Journal of Fluid Power, 2019 This paper studies a variable speed drive with two hydraulic pump motors connected to an actuator. The torque load of the pump motors is reduced by connecting different pressures to the inlets of the pump motors. A method for real-time selection of the inlet pressures is developed.
