this paper presents a novel control method to improve the efficiency of low-voltage dc-dc converters at light loads. pulse width modulation (pwm) converters have poor efficiencies at light loads, while pulse frequency modulation (pfm) control is more efficient for the same cases. switching losses constitute a major portion of the total power loss at light loads. to decrease the switching losses...

In this paper, Performance of three-level integrated ac–dc converter with Hysteresis Current Control Technique is presented. The proposed converter combines with the operation of the boost power factor correction and the three-level dc–dc converter. By the implementation of Hysteresis Current controller, the switching sequence is under controlled condition and the output voltage of the proposed...

In this paper, a three-level integrated ac–dc converter with power factor correction is presented. The proposed converter integrates the operation of the boost power factor correction and the three-level dc–dc converter. The converter is made to operate with two independent controllers—an input controller that performs power factor correction and regulates the dc bus and an output controller th...
