摘要
根据常用电子变压器的电磁兼容性和安全方面的新要求,对其基本线路进行改进设计和分析.在输入端加入了滤波网络和输入保护电路,并加入了实用的输出保护电路,既实现了220V输入、12V/60W输出的功能,又大大提高了电子变压器的性能,达到了IEC制定的技术标准.通过理论和实验分析,证明了该设计的优点,给出了元件参考参数.本电路设计具有实用性,适用于工业化生产.
According to new requests of common electronic transformers’ electromagnetic compatibility and security,its basic circuit was improved and analyzed.Puts a filtering net and a protective circuit of input was put in the front of the whole input net,and a new protective circuit of output was designed.This design realizes that 220 V input is transformed into 12 V/60 W output,and improves the performance of device to reach the criterion of IEC.The strongpoint of the new design was proved with analysis of theory and experimentation,and the tried parameters were provided.It is fit for producing because of its practicality.
