| 摘 要： | 对串.串补偿的松耦合谐振变换器进行了研究.在忽略谐波的条件下,根据正弦等效原理,推导出输入电压和输出电压的关系式,利用归一化的分析方法并借助Matlab仿真软件,计算得出工作频率、负载和耦合系数对输出电压的关系曲线.推导并计算出系统发生频率分叉现象时次级品质因数的临界值,得出重载时该变换器会发生频率分叉现象,并给出在某种情况下补偿电容和工作频率的合理选择.最后,基于实验样机进行了实验验证.

| Abstract: | The series-series compensated loosely coupled inductive power transfer full-bridge resonant converter is studied.In the condition of neglecting the harmonious waves,the relationship between the input and output voltage is deduced according to the sine equivalence principle.In virtue of the normalized analysis method and Matlab,it is deduced that the output voltage is influenced by the switching frequency,the load and the coupling coefficient.Then the marginal value of secondary quality factor is derived whe... |
