线路通断检测器的设计:
1.用压电陶瓷蜂鸣片作为电声元件。
2.用两根导线作为测试探针
3.线路通断是通过测试电阻的大小来判断,有以下三种情况:
(1)若150Ω<Rx<900Ω,则蜂鸣片不发出声响。
(2)若Rx>900Ω或者Rx<150Ω,则蜂鸣片发出间歇式的滴-滴声响。
以上各临界阻值(150Ω和900Ω),允许误差±10%
4.+15V直流稳压电源需要设计。
(Line-off detector design:
1. Piezoelectric ceramic buzzer as the electro-acoustic components.
2. As a test probe with two wires
3. Lines off by testing the resistance to determine the size, the following three conditions:
(1) If 150Ω <Rx <900Ω, the buzzer is not audible.
(2) If Rx> 900Ω or Rx <150Ω, then the buzzer sent intermittent drip- drip sound.
Above the critical resistance (150Ω and 900Ω), tolerance ± 10
4.+15 V DC power supply need to design.

死区补偿原理与实现
做项目的时候在ST的库上加死区补偿,整理了一些前期做的准备工作内容,上传的是压缩的PDF文件。有需要的可以看看,不是成品,不是程序,只是一点点想法。(The theory of dead time compensation in motor control. The file is a PDF. it is only the comprehension of myself about this function.)
