A simple current sharing control technique for the switching power supply is presented herein, which is based on the concept of the differential-mode transformer. This current-sharing structure is very simple as well as makes the efficiency relatively high at light load, and this is quite suitable for industrial applications with standby power considered. In addition, a synchronously-rectified (SR)...
A simple current-sharing control technique for the switching power supply is presented herein, which is based on the concept of the differential-mode transformer and which makes the load current evenly shared well among phases all over the line voltage and load current ranges. This current-sharing structure is very simple, and it makes the efficiency relatively high at light load, which is quite suitable...
In this paper, a two-stage-cascaded scheme is presented to charge two Li batteries. The first stage consists of a boost converter which is used to step up the input voltage to some value and takes voltage-mode control, whereas the second stage is comprised of two paralleled buck converters which are used to charge two Li batteries under voltage-mode control and constant current control. Above all,...
