几种常用的防反接电路

在项目中,经常要考虑反接保护。因为很多时候出于成本、空间考虑,有的板子接口是没有使用防呆接口的。并且我还遇到过大力出奇迹的现象,即连线的时候明明用了防呆接口,却被大力出奇迹给反着硬怼上去了。

1.串联二极管

利用二极管的单向导通,将二极管串联到电源的主回路中。这么做需要考虑二极管的载流能力、正向压降。

串联二极管的电路简单,但是在工作时会损失一部分电压,例如PIXHAWK2.4.6的供电UBEC使用的是5.3V,这是因为PIXHAWK2.4.6的供电主回路里串联了一颗正向压降为0.3V的二极管。

2.并联二极管

同样也是利用二极管的单向导通特性,将二极管并联在电源两端。当电源接反时,二极管形成短路,保护后级电路。至于电源嘛,交给天意了。

并联二极管的电路也十分简单有效,该电路相比串联二极管电路效率更高,二极管在正接时不起作用,只有反接才起作用。至于有些工程师可能会考虑电源短路会如何,我想大部分电源应该都会有短路保护吧,如果是动力电池的话,短时间短接放电问题也不大。相比娇贵的控制电路,电源电路即使受到损坏,也把成本降低下来了。

3.串联MOS管

将MOS管按照体二极管的方向串联到电路中。以NMOS为例,栅极连接电源正(如果电源电压过高,需要串联一个分压电路,以及并联钳位二极管来保护栅极),漏极连接电源负,源极连接负载负。

可以分析,系统在刚上电的时候,电流通过体二极管形成导通,此时GS之间会产生一个电压差,因此MOS管导通。MOS管导通之后由于MOS管内阻极低,可以认为体二极管关闭,电流从MOS管经过。

如果接反,体二极管截止,Vgs不会产生电压差,因此MOS管关断,电路断路。
