<p>A system for transferring energy from an energy source includes a first energy source 12, a DC link coupled to a DC load, a first DC-to-DC voltage converter 14 coupled to the DC link, and a second DC-to-DC voltage converter 20,22 coupled to the first energy source 12. A controller 84 is coupled to the first 14 and second 20,22 DC-to-DC voltage converters and configured to determine a voltage level of the first energy source 12 and of the DC link. If the voltage level of the DC link is less than the voltage level of the first energy source 12, the controller 84 controls the second DC-to-DC voltage converter to draw energy from the first energy source to cause the DC voltage output from the first energy source and supplied to the first DC-to-DC voltage converter to be below the DC load voltage supplied to the DC link via the first DC-to-DC voltage converter.</p> |
