在文献中，研究和介绍了几种AC/DC变换器。本主题涵盖了所有类型的拓扑和技术。这包括单开关、半桥和全桥拓扑以及硬、准谐振和谐振开关。还开发了不同的技术来控制这些转换器，以确保高功率因数。本文的目的是为低功耗应用提供一个低成本的解决方案。介绍了一种符合en61000 -3-2标准、适用于300w功率范围的高频交直流变换器。它的拓扑结构是基于全桥串联谐振转换器，其工作频率低于谐振频率的一半。转换器的特点是零电流的开启和关断，并减少了输出整流器的开关电流。这些优点使得串联谐振拓扑结构适用于高频工作。因此，由于电感和电容值在该频率范围内相对较小，因此成功地应用了LCT网络（电感-电容-变压器）的电磁集成。给出了计算机仿真和实验结果。
In the literature, several AC/DC converters are studied and presented. All kinds of topologies and techniques are covered under this topic. This includes single-switch, half-bridge and full bridge topologies as well as hard, quasi-resonant and resonant switching. Different techniques are also developed to control these converters ensuring high power factor. The aim of this paper is to present a low-cost solution for low-power applications. A high-frequency AC to DC converter that respects the EN 61000-3-2 standard and is suitable for applications in the power range of 300 W, is presented. Its topology is based on a full-bridge series-resonant converter that operates below half the resonant frequency. The converter features zero-current for both turn-on and turn-off and reduces the switching current for the output rectifier. These advantages make the series-resonant topology suitable for operation at high frequency. Thus, electromagnetic integration of the LCT network (inductor-capacitor-transformer) is successfully applied owing to the fact that the inductor and the capacitor values are relatively small at this range of frequency. Computer simulation and experimental results are presented.
