Performance of Three Level Integrated AC-DC Converter with Hysteresis Current Control
نویسنده
چکیده
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 converter is effective. The converter is made to operate with two independent controllers which are combined in a single converter. Input controller does PFC and regulates dc bus, output controller regulates the output voltage while still allowing a single stage converter topology is used. Converter operation is explained and evaluated in terms of control strategy and total harmonic distortion of input current. Finally the converter with current mode control is compared with that of converter with voltage mode control techniques. Keywords—AC-DC Converters, Hysteresis Current Control (HCC) Technique, Three level Converters, PFC (Power Factor Correction), Single Stage Converters.
