摘要
以效率为优化目标,以品质因数Q、励磁电感与谐振电感的比值h以及磁性元件的工作磁通B_(max)为优化变量,详细给出了实现最优设计的各个步骤,包括损耗建模、边界条件的推导以及最优解的求解流程.最后制作了一台100 kHz、300 W的样机.给出了最优设计与可行设计的理论与实验对比结果.实验结果证明了该最优设计方法的有效性和准确性.
In the process of optimization,the Q factor of the converter,the h ratio of magnetizing inductance to resonant inductance and the maximum flux B_（max） were chosen as the optimal parameters,the details on the power loss of the converter was presented,the boundary conditions was deduced and the process of getting optimum solution was proposed.Finally,a three-hundred-watt prototype was build;the theoretical and experimental comparison result verified the feasibility and accuracy of the design method.
