Abstract
A method of reducing switching losses in a switch array for an output regulator, the switch array to convert energy from an input source to a regulated output of the output regulator, the switch array including at least two power switches, includes determining an expected current flowing through the switch array during a next switching cycle, at a sampling rate, determining expected power losses of the switch array based on the expected current, determining a combination of the power switches to enable that minimizes the expected power losses, and enabling the combination of power switches.

A method of reducing switching losses in a switch array for an output regulator, the switch array to convert energy from an input source to a regulated output of the output regulator, the switch array including at least two power switches, comprising:
- a) determining an expected current flowing through the switch array during a next switching cycle;
- b) at a sampling rate, determining expected power losses of the switch array based on the expected current;
- c) determining a combination of the power switches to enable that minimizes the expected power losses;
- and
- d) enabling the combination of power switches.
