ROBUST AVERAGE CURRENT MODE ELECTRONIC CIRCUIT FOR SWITCHED DC-DC CONVERTERS, AND METHOD

摘要

The invention consists in adding to the conventional average current mode control loop (with two regulators, the voltage regulator and the current regulator) a third auxiliary regulator which is easily implementable by means of operational amplifiers, thereby providing improved dynamics characteristics to switched DC-DC and AC-DC converters which are controlled by pulse width modulation (PWM) and are derived from the Buck topology, and to other converters with minimal phase dynamic characteristics and to distributed power systems resulting from the combination of the former converters.
