Abstract
Described is a controller for a DC/DC converter of a type having N power stages, where N is a natural number greater or equal to 2. The controller comprises a decision maker module, a proportional-integral-derivative (PID) or proportional-integral (PI) control module and a transient compression control module. The decision maker module determines a first steady state mode of operation and a second transient mode of operation and is configured to switch control between said first steady state mode of operation to said second transient mode of operation when an operating parameter of one of the N power stages exhibits a predetermined operating condition relative to a predetermined operating limit and/or a predetermined, calculated or selected threshold. The PID or PI module regulates the operating parameter during said first steady state mode of operation. The transient compression control module limits any overshoot, undershoot or imbalances of the operating parameter levels during said second transient mode of operation.
