Patent ID: 8848399

Claim:
A power converter having a switching frequency of at least 30 MHz, the power converter comprising: an inverter stage for receiving an input and generating an inverter output, wherein the inverter stage comprises an inverter switch configured to switch the inverter stage; a synchronous rectifier stage for receiving the inverter output and for delivering an output of the power converter to a load, wherein the synchronous rectifier stage comprises a synchronous rectifier switch configured to switch the synchronous rectifier stage; and a controller configured to control the output of the power converter by modulating the at least one of the inverter stage and synchronous rectifier stage on and off at a frequency less than a switching frequency of at least one of the inverter stage and the synchronous rectifier stage, the controller being further configured to adjust, independently of an amount of power delivered to the load, one or more of a duty cycle of the inverter switch, a duty cycle of the synchronous rectifier switch, and a phase between the switching of the inverter switch and the switching of the synchronous rectifier switch.
