技术资料 重复控制理论在无速度传感器永磁同步电机自学习控制中的应用
This study presents a solution to control a PMSM without sensors. The control method is the presented
superposition principle. This method of sensorless theory is very simple to compute estimated angle. Therefore,
computing time to estimate angle is shorter than other sensorless methods. The use of ...
技术资料 ELIS-1024 线性图像传感器
The ELIS-1024 Linear Image Sensor consists of an array of high performance, low dark current photo-diode
pixels. The sensor features sample and hold capability, selectable resolution and advanced power
management. The device can operate at voltages as low as 2.8V making it ideal for portable appli ...
技术资料 Specifying the Jitter Performance
The question of sample-clock quality is a perennial one for digital audio equipment designers. Yet most chip makers
provide very little information about the jitter performance of their products. Consequently, equipment designers
sometimes get burnt by jitter issues. The increasing use of packet-bas ...
电源技术 DN1011 简单高效率隔离型反激式电源
 
While simplicity and high effi ciency (for cool running) areno longer optional features in isolated power supplies, itis traditionally diffi cult to achieve both. Achieving higheffi ciency often requires the use of advanced topologiesand home-brewed secondary synchronous rectifi cationsch ...
电源技术 DN458降压转换器简化低电压设计
 
Many system designers need an easy way to producea negative 3.3V power supply. In systems that alreadyhave a transformer, one option is to swap out the existingtransformer with one that has an additional secondarywinding. The problem with this solution is that manysystems now use transfor ...
