摘要
对高频零电流软开关进行了理论分析,给出了开关中各参量的数学关系。通过对开关中能量传导的研究,得出了在一定条件下求解开关频率的近似公式。同时,探讨了零电流开关应用于开关电源中的特点与谐振参数的限制条件。对样机的测试表明,该分析对高频电源的设计具有指导意义。
In this paper,ZCS(zero current switch) worked in high frequency is studied.The mathematical relationships of every parameter in the switch are given.By analyzing the energy transfer in the switch,the approximate fomula are got to find out the work frequency under a certern condition.Mean while,the characteristics of its application and some restriction of the resonant parameter are discussed.Finally,the measured data of the experiment indicates that the analysis is close to reallity.
