Abstract

An energy recovery system for machines each having a mechanical power transmission system that generate energy in a first portion of a mechanical power transmission system cycle and draw energy from an energy source in a second portion of the cycle incudes a power distribution assembly configured to receive energy generated during the first portion of the cycle, a plurality of actuator controller devices configured to selectively output energy to a corresponding actuator of each of the plurality of machines, each of the plurality of actuator controller devices electrically coupled to the power distribution assembly and configured to reuse energy received by the power distribution assembly, and, a controller for each of the plurality of actuator controller devices programmed to adjust the output energy of the corresponding actuator controller device to substantially maintain a voltage level of the power distribution assembly relative to a voltage level setpoint.
