ABSTRACT:
A power supply system includes a first driver circuit to control a corresponding switching of a first switch device and a second switch device in the power supply system via different drive circuits. To reduce losses and thus improve efficiency of the power supply system, a first driver circuit can be configured to initiate a faster rate of transitioning the first switch device between ON and OFF states than a second driver initiates transitioning of the second switch device between ON and OFF states. To reduce the effects of introducing unwanted ripple voltage on an output signal used to drive a dynamic load, a controller in the power supply system can be configured to initiate shedding or adding of multiple voltage converter phases at the same time when load requirements cross a threshold value.
