ABSTRACT
For this type of integrated system, the boost converter is in the front and is followed by another basic non-isolated or isolated converter. Both of them share one active switch. The output of the boost converter will be used as the input source for the second converter. When the switch is on, the boost inductor is charged. The second converter will also work in the switch-on state. When the switch is off, the inductor is discharged. The sum of the input source energy and the inductor storage energy will be transferred to the boost output [1]–[7].
