Abstract
An integrated converter with single-ended control and power factor correction includes an input unit, a boost inductor, a voltage regulator, an energy-storing capacitor, a buck-boost converter, a single-ended switch and a control unit. The voltage regulator and the buck-boost converter share the single-ended switch and the control unit in order to correct power factor, reduce output ripple, simplify the complexity of circuit and decrease the number of components. The voltage regulator is utilized in reducing the frequency of switching and the conductive losses, thus improving overall performance. With the magnetic loop, the transformers of the boost inductor and the voltage regulator can be merged, and thus the efficiency of the whole spatial usage is increased and the noise interference is reduced.
