TI’s Ultrasonic Sensing Technology for Flow Measurement

The ultrasonic sensing technology uses the time-of-flight (TOF) of the ultrasonic wave to correlate with the velocity of the medium in the pipe section, and obtains the time difference between the upstream and downstream directions of the ultrasonic wave, and finally measures and calculates the flow rate. This technology is excellent for measuring a wide range of flow rates and is capable of handling liquids such as water and oil as well as gases such as methane.

UC3902 Application Circuit

Warm hints: The word in this article is about 1627 and  reading time is about 12 minutes.  
Guidance: There are many parallel connection schemes for DC modules, but there are some drawbacks when they are used in power operation power supply: for example, the current sharing accuracy of output impedance method is too low; neither master-slave setting method nor average current method can realize redundancy technology, so that the reliability of parallel power supply module system can not be guaranteed well; and the independent current sharing method is based on its own characteristics. Performance, such as "high current sharing accuracy, good dynamic response, redundancy technology can be achieved", is increasingly favored by the majority of product developers.

What is Field Effect Transistor

Warm hints: The word in this article is about 587 and  reading time is about 5 minutes. 
Guidance: Field effect transistor (FET) is abbreviated as field effect transistor. Generally, transistors are conductive by two kinds of polar carriers, i.e. most carriers and a few negative carriers. Therefore, they are called bipolar transistors, while FET is conductive only by most carriers. It is opposite to bipolar transistors, it is also called unipolar transistors.
