Circuit for improved load transient response in power supplies

摘要

An apparatus contains a main electrical supply and an additional electrical supply for supplying additional electrical current in response to a change in an output load supplied by the main electrical supply. A differential measuring device senses a change in the load, or output of the main supply, and provides an indication to the additional electrical supply to supply additional current to the load. The additional electric supply contains a capacitor connected to a voltage source having a higher voltage output than the main electrical supply, and a current generator.
