POWER CONVERTER APPARATUS AND METHOD WITH COMPENSATION FOR LIGHT LOAD CONDITIONS

A switch mode power converter provides high efficiency at light and no load conditions by utilizing a variable inductance swinging choke at the output of a synchronous rectifier. The use of the swinging choke with a synchronous rectifier eliminates power inefficiencies caused by currents that circul...

Zusammenfassung:	A switch mode power converter provides high efficiency at light and no load conditions by utilizing a variable inductance swinging choke at the output of a synchronous rectifier. The use of the swinging choke with a synchronous rectifier eliminates power inefficiencies caused by currents that circulate from the output capacitance to the input capacitance during no load conditions.
