Abstract

An adaptive power system includes an energy source, a bidirectional current source electrically connected between the energy source, and a power distribution bus of a power distribution system. The bidirectional current source delivers and absorbs power from the power distribution system to buffer a dynamic load profile of a dynamic load. The adaptive power system also includes a control loop and signal filter to control the bidirectional current source and regulate energy stored in the energy source.
