H桥电机驱动器工作原理
在日常生活中的电动车窗，折叠后视镜，天窗，座椅控制和许多类似系统，都是通过简单的直流电机运行。这样继电器控车辆中的各种电机。
因为驱动继电器很简单，与之相比MOS在噪声，使用寿命，尺寸和可靠性方面要优越的多，因此使用MOS代替继电器始终是更好的选择，此外继电器无法控制电机的电流，控制电机是通过H桥网络实现的。
最简单的驱动桥是PWM，通过可变占空比的控制信号改变转速。
双极驱动允许同时打开两个MOS管，正向运行。
反向运行，通过不管的MOS管导能改变电机的正反转，通过PWM占空比改变其速度。
I would like to thank you for the efforts you’ve put in writing this site. I really hope to check out the same high-grade blog posts from you in the future as well. In fact, your creative writing abilities has inspired me to get my very own site now 😉
That is a very good tip particularly to those fresh to the blogosphere. Simple but very accurate information… Many thanks for sharing this one. A must read article!
This is a topic that is near to my heart… Thank you! Exactly where are your contact details though?
Pretty! This was an incredibly wonderful post. Many thanks for supplying this information.
I’m amazed, I have to admit. Seldom do I come across a blog that’s both equally educative and engaging, and let me tell you, you have hit the nail on the head. The problem is something too few men and women are speaking intelligently about. I am very happy I found this during my search for something relating to this.

The problem is something too few folks are speaking intelligently about. Now i’m very happy that I came across this during my search for something regarding this.
The next time I read a blog, I hope that it does not fail me as much as this particular one. I mean, I know it was my choice to read, however I truly believed you would probably have something interesting to talk about. All I hear is a bunch of crying about something that you could fix if you weren’t too busy searching for attention.
I’m very pleased to discover this great site. I want to to thank you for your time due to this wonderful read!! I definitely really liked every part of it and i also have you saved as a favorite to check out new stuff on your website.
Excellent web site you’ve got here.. It’s difficult to find high quality writing like yours nowadays. I honestly appreciate people like you! Take care!!
The very next time I read a blog, Hopefully it does not fail me as much as this particular one. I mean, I know it was my choice to read, but I really believed you’d have something helpful to say. All I hear is a bunch of complaining about something that you could possibly fix if you were not too busy seeking attention.
