Abstract

The time when a switch is turned on from the time of one voltage valley to the time of another voltage valley may be adjusted for controlling an average load current or average load voltage. In some examples, the adjustment is instantaneous, and in some examples, the adjustment is gradual. Both of these example techniques provide for high switching efficiency of the switch.
