Abstract

Key Words: Droop Compensation, Converter Response, Converter Transient Response, Converter Output Error Background A power converter's output needs to provide a nearly constant output voltage to a load. In some applications, the converter is required to maintain a nearly constant output voltage for a sudden step change in load current. For example, a computer has a "power-saving mode" in which a number of circuit sections are turned off to reduce current consumption to near zero. Where required, these sections are turned on, resulting in the load current increasing to a high value within a few hundred nanoseconds.
