Abstract
A supplemental power supply includes output terminals configured to provide power to an external load, first input terminals configured to receive power from a first power supply, and second input terminals configured to receive power from a second power supply, the second power supply independent from the first power supply. Further, a charge coupling and decoupling circuit (CCDC) is electrically coupled to the output terminals and first and second input terminals, the CCDC configured to electrically couple one of the first input terminals or the second input terminals to the output terminals, and electrically couple or decouple the first input terminals from the second input terminals.
Claims18
A supplemental power supply, comprising:
- output terminals configured to provide power to a load;
- first input terminals configured to receive power from a first DC power supply;
- second input terminals configured to receive power from a second DC power supply, said second DC power supply independent from said first DC power supply;
- and
- a charge coupling and decoupling circuit (CCDC) electrically coupled to said output terminals and first and second input terminals, said CCDC configured to
- electrically couple a one of the first input terminals or the second input terminals to the output terminals so as to provide electric power from the first or second DC power supply to the load, and
- electrically couple or decouple the first input terminals to/from the second input terminals so as to charge the second DC power supply from power provided by the first DC power supply when the first DC power supply is powering the load.
A method for providing power to a load via a supplemental power supply, said supplemental power supply including a first DC power supply and a second DC power supply independent from the first power supply, comprising:
- determining a charge level of the first power supply relative to the second power supply;
- electrically coupling one of the first power supply or the second power supply to the load based on the determined charge level of the first and second power supplies;
- and
- charging the second power supply from the first power supply.
