简介：参加智能车竞赛的同学提出了一个问题，也就是使用自制的铝基电路板制作的LCC接收电路为什么出现了烧毁无线发送线圈的情况？关于这个问题需要后期通过试验测试，检查究竟是电路参数设计问题还是铝基电路板自身带来电路损耗。

初步问题分析

§01 问题提出

卓大，为了散热，我用了铝基板做无线充电，接电容发现充不上电，然后灯就烧了。铝基板不能用来做无线充电吗？

▲ 图1.1 制作的铝基板的LCC接受电路板

下面是LCC接受电路板上的各个元器件的参数：

输出电感用400股的利兹线饶的。
整流的肖特基也SVM1550UB，额定电流为15A
后面那个肖特基为STPS40L45CC额定电流为20A

▲ 图1.2 LCC电路的参数设计

当时接超级电容时发现二极管不烫，然后主要是超级电容两段电压不变，再放一会灯就烧掉了，超级电容我也测过能冲进去电的。

PCB整体布局就是这样，整流桥我刚换过没来得及改：

▲ 图1.3 铝基板的PCB布局

§02 问题分析

一、初步问题分析

造成信标灯损坏的原因是：？

LCC电路参数问题？
接受电路制作存在的缺陷；
铝基电路板造成的额外影响。

这部分需要逐一通过试验和分析来确认。
