Abstract
An energy transfer circuit for connecting a load to multiple energy sources that can have different voltages. The energy transfer circuit connects the load and at least two energy sources, and has a control unit. The energy transfer circuit can transfer energy from at least one energy source to the load in response to the load's power demand; transfer energy from the load to at least one energy source in response to the load's charging current, and transfer energy between the energy sources. The energy transfer circuit also includes a first capacitor in parallel with the primary source and the load; a second capacitor in parallel with the secondary source, an inductor, a first switch between the inductor and the first capacitor, a second switch between the inductor and the second capacitor. The control unit opens and closes the first and second switches in response to the load and sources.
