Abstract:
A system that seamlessly places an additional power source (P1) in series with a first source (PD) while said source PD supplies a load with power when additional power is required by said load, said system comprising:a first source (PD) for supplying said load with power; a second source (P1) for supplying said load with additional power; and a controller that electrically couples said second source seamlessly in series with said first source (PD) such that, while said first source (PD) supplies power to said load said second source (PL) is seamlessly placed in series with said first source (PD) to significantly increase power to said load, wherein said first source (PD) is coupled to at least two series-connected circuit elements that each supply a portion of said power to said load; wherein said controller couples said second source (PL) in parallel with at least one of said circuit elements and then uncouples at least one of said circuit elements from said second source (PL) thereby seamlessly placing the at least one of said circuit elements of the at least two series-connected circuit elements of said first source in series with said second source (PL).
