A two-stage power factor correction converter typically employs a cascade configuration of a pre-regulator boost power factor correction converter with average current mode control to achieve a near unity power factor and a tightly regulated post-regulator DC-DC Buck converter with voltage feedback control to regulate the output voltage. Based on the assumption that the tightly regulated postregulator DC-DC Buck converter is represented as a constant power sink and some other assumptions, the simplified model of the two-stage power factor correction converter is derived and its approximate periodic solution is calculated by the method of IHB. And then, the stability of the system is investigated by using Floquet theory and the stable boundaries are presented on the selected parameter spaces. Finally, some experimental results are given to confirm the effectiveness of the theoretical analysis.展开更多

The theory of international communication originated in the West. In the new era, many of its theoretical perspectives need to be reviewed and re-evaluated. Compared with other communication patterns such as mass communication, international communication is highlighted by notable characteristics such as its concern for core national interests, distinctive strategic objectives and e ective changes. It offers a new approach to showcasing comprehensive strength among countries and regions. The development of international communication theory can be divided into three main stages. One prominent contribution of the established theoretical achievements lies in its re ning of multiple important general laws of international communication based on the actual needs and its forming of a theoretical system. The major limitation is that these theoretical achievements, under the influence of Western centralism, place excessive emphasis on competition while paying scant attention to accommodation and mutual learning. In the face of new characteristics and practical requirements in the new era, international communication theory should be equipped with a broader vision for more breakthroughs and innovations.展开更多

Angel Clare, as one of the main male characters, has always been neglected. Exploring Angel's mental process and choices from the perspective of Lacan's mirror stage theory will provide a new interpretation of this novel, and a deeper understanding of the aesthetic value and the purpose of the characterization might be formed, and Hardy's concerns for the gender issues in the Victorian age have also been well presented through the time-transcending character.展开更多
