摘    要:基于变压器的一般原理和结构出发,提出了变压器分布电容的形式和有关数据分析,并用特制线圈模拟变压器绕组,通过实验找到一些固有参考数据,进一步用外变频法确定绕组内参数变化曲线,从曲线图上找到一个特殊点,证明该极点就是由分布电容引起的谐振点。根据该极点的特点及参数可大概计算出分布电容及Q值,认为分布电容在高频下对变压器的影响不可忽视,要积极采取措施阻止其对变压器的破坏。

关 键 词:微型变压器  分布电容结构  高频谐振  不可忽略性

Abstract:According to the general principle and structure of transformer,this study presented a new model of distributed capacitance(DC) and simulated a kind of winding use of special circles.Variety circus of inherent-parameters in winding with alternating frequency method were obtained by means of the experiments.A special point in the circus was chosen and proved resonant point which was resulted from distributed capacitance.And then distributed capacitance and Q circuit were cauculated according to the character...
Keywords:micro-transformer  distributed capacitance  resonant  nonignore
