Patent ID: 8614555

Claim:
A system comprising: an actuator control system comprising: a controller configured to direct power from a power source to a particular actuator, wherein the particular actuator is coupled to a control device to apply a force related to operation of a vehicle, wherein the controller includes a network of transistor nodes; and a buck-boost circuit configured to direct excess power generated by the particular actuator to an energy storage device when an actuator power level of the particular actuator is greater than an anticipated power level, wherein the buck-boost circuit includes an inductor coupled in series with a diode and includes a switching device that is coupled to a relative ground, wherein energy is accumulated at the energy storage device when the switching device is in a first mode, and energy is drawn from the energy storage device when the switching device is in a second mode, and wherein the buck-boost circuit is coupled to an output of the network of transistor nodes.
