The original intention is that the light will turn on when the key is pressed, but the microcontroller pins are burned during the test. I don't know why? I hope you can give me some advice! Thank you!...
[font=微软雅黑][size=14px]When drawing a schematic in AD, I don’t know the name of the component I need, and there are many components that are not in the component library. What should I do? [/size][/fon...
I only had experience learning about cortex-M3 before, but recently I bought a 430 LaunchPad from a group and was able to make some small programs according to the routines.
It's a bit difficult to re...
Some time ago, I attended the 4th Energy Chemistry Forum of the Chinese Chemical Society and learned about high-energy-density and high-safety batteries. I would like to summarize and share this wi...[Details]
The difference between a series inverter and a parallel inverter is that they use different oscillation circuits. A series inverter connects L, R, and C in series, while a parallel inverter connect...[Details]
Lithium-ion batteries are a key component of electric vehicles. Their high energy density enables them to store a large amount of energy in a relatively compact and lightweight package, which is cr...[Details]
Generally not, but there are exceptions. For example, a torque motor controller with three-phase output voltage imbalance can cause current imbalance, similar to a phase loss. However, only two pha...[Details]
While aberration theory is a vast subject, a basic understanding of some fundamental concepts can make it easier to understand: spherical aberration, astigmatism, field curvature, and chromatic abe...[Details]
The basic structure of the power grid dispatching automation system includes three parts: control center, master station system, plant terminal (RTU) and information channel. According to the diffe...[Details]
Silicon carbide (SiC) power switching devices are becoming a popular choice for industrial battery applications due to their ability to achieve faster switching speeds and superior low-loss operati...[Details]
What is the difference in response time when the output uses cyclic refresh and direct refresh?

01 Introduction
The SINAMICS V20 inverter controls three-phase AC asynchronous motors. Depending on the size (frame sizes FSA to FSD), the power range of the three-phase AC 400V inverter cover...[Details]
After suspending its autonomous driving business for a period of time, General Motors chose to return to the track. In the past, GM hoped that its Cruise would leap into L4 autonomous driving - no ...[Details]
Under the guidance of the "dual carbon" goals, vehicle-to-grid interaction (V2G), an innovative model that achieves deep integration of new energy vehicles and power grids, is steadily moving from ...[Details]
