## Abstract This letter presents a singleโstage softโswitched fullโbridge AC/DC converter for lowโvoltage/highโcurrent output applications. A phaseโshifted method with a variable frequency control is used to regulate the DC bus voltage and the output voltage of the singleโstage AC/DC converter. The
Series resonant dc-dc converters possess the advantage of high efficiency for a relatively wide load range because their circulating energy is small. However, it is often observed that the switching frequency varies greatly when the input voltage and load current change, and in particular that the s
