ABSTRACT:
A power converter output voltage regulation method in which sensed output voltages and sensed currents are stored in a memory during a plurality of time intervals. In each time interval the sensed output voltage and the sensed current is compared with the sensed output voltage and sensed currents in time intervals previously stored in the memory. If preceding data are found to match the most recent data, an open loop response is applied. If the most recent data and stored previous data do not match, a closed loop response is applied.
