Abstract
An apparatus comprises a switching power circuit and a control circuit. The switching power converter circuit includes an output port for electrical coupling to a variable load, an input port for electrically coupling to a first energy source, wherein the energy density of the first energy source is insufficient to meet a peak energy requirement of the variable load, an input/output port for electrical coupling to a second energy source, and one inductor electrically coupled to the input port and a circuit node, wherein the electrical coupling is non-switchable. The control circuit is configured to charge the inductor using the first energy source via the input port, to provide energy from the inductor to the load via the output port, and to provide both of, via the input/output port, energy from the inductor to the second energy source and energy from the second energy source to the variable load.
