Title:
AN ADAPTIVE CONTROLLER FOR CONTROL OF A DC-DC POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2011/101341
Kind Code:
A3
Abstract:
The present application provides a tunable compensator providing a control signal to control a switch in a power supply. A measurement is taken of the level of activity of the control signal. This measurement is used to introduce a bias into a tuner tuning the compensator when the amount of activity in the control signal drops.
