ABSTRACT:
An aircraft electrical energy supply bus supplementing arrangement based on large capacitor or super capacitor storage of electrical energy for bus supplementation. Supplying of bus energy to the large capacitor is addressed in the invention. In this supplying energy is removed from the aircraft bus during quiescent conditions under the control of a energy coupling circuit which has a plurality of different energy removal rates, rates which are selected in response to the yet needed amount of capacitor charging and in a time-constant-controlled manner. Feedback control of this charging time constant selection is employed along with passive electrical device dissipation of major fractions of the time constant apparatus energy losses.
