| 摘 要： | 反激变换器中高频变压器是核心部件,其效率直接关系到变换器的效率,因此优化设计高频变压器就成为提高效率的关键。通过对反激变压器绕组采用不同结构时所带来不同的涡流损耗和漏感进行分析,得到本文所设计绕组结构二维模型。利用有限元分析软件进行数值仿真,获得的数据证明此模型是可行的。制作出实验样机对其进行实验比较,验证了所设计的高频变压器绕组结构合理,漏感小,效率高,输出的电压的谐波含量低。 |

| Abstract: | High-frequency transformer is the key component of the flyback converter, and its efficiency is directly related to the converter. In order to improve the inverter＇s efficiency, the optimum design of high-frequency transformer becomes very important. A 2D finite element model of the winding structure is built up to calculate the eddy current losses and leakage inductance caused by the different structure of flyback transformer winding. The laboratory prototype of the high frequency transformer has been designed, and the experimental results show that the transformer winding structure is reasonable, low leakage inductance, high efficiency and perfect output voltage waveform. |
| Keywords: | high frequency transformer leakage inductance winding eddy current loss |
