Abstract:
1. regulator circuit architecture including a regulated branch including, at least one regulated voltage converter, an unregulated branch including at least one unregulated voltage converter having a lower output impedance than said regulated branch, said unregulated branch being connected in parallel with said regulated branch, wherein output impedances of said regulated branch and said unregulated branch determine a proportionate load current delivered to a load from each branch, and two power supplies, a first power supply of said two power supplies supplying input power to said regulated branch and a second power supply of said two power supplies supplying input power to said unregulated branch and connected such that variation in input voltage to said unregulated branch due to load current supplied therefrom provides feedback to the regulated branch for voltage regulation of the output voltage of said voltage regulator circuit.
