The computer system is 64-bit, MPLAB IDE v8.80 and the compiler are C:\Program Files\HI-TECH Software\PICC\9.82\bin 9.82. Why does the compile error occur? I have installed many versions but none of t...
How to be a Star Engineer Robert E. Kelley, Carnegie Mellon University (Robert E. Kelley, "How to be a star engineer," IEEE Spectrum, pp. 51-58, Oct. 1999.) In 1985, I was asked some questions, and si...
I would like to ask, why do we have to remove the motherboard before burning the flash? Wouldn't it be very troublesome to mass produce or change it?...
Flip-chip and ball grid array (BGA) are two widely used packaging technologies in the electronics industry. Each has its own advantages and limitations, and in some cases, they can complement each ...[Details]
Electric motors and internal combustion engines of the same power have similar torque levels. High power requires high torque, and torque determines a vehicle's acceleration speed, commonly known a...[Details]
In recent years, with the application of the IEC61850 standard and the development and deployment of optoelectronic transformers, the concept of digital substations has been put into practical use ...[Details]
Current Development Status of DVR Market
A DVR, or digital video recorder, uses a hard disk for recording, unlike traditional analog video recorders. It's often called a DVR because it's a com...[Details]
According to foreign media reports, BMW has just been granted a patent for a screen that could cover the entire roof. BMW hopes to transform at least a portion of the vehicle's headliner into a dis...[Details]
Through AI connection technology supported by Qualcomm X85 5G modem and RF and Qualcomm FastConnect 7900 mobile connection system, seamless switching can be achieved between cellular net...[Details]
With the advancement of science and technology and the promotion of green, energy-saving, and circular development, the demand for precise control and accurate measurement is increasing. In the pow...[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]
0 Introduction
With a rapidly aging population, a young couple is now required to care for an increasing number of elderly people, leading to a growing difficulty in providing care for them. E...[Details]
We know that the power output by the engine does not directly act on the wheels to drive the car, but needs to pass through a series of power transmission mechanisms. So how is the power transmitte...[Details]
The transition to SDVs (software-defined vehicles) involves more than just replacing parts; rather, it involves the organic connection of various elements, from internal vehicle systems to ext...[Details]
Anyone who has driven a pure electric vehicle will find that it starts much faster than a fuel vehicle. So why do pure electric vehicles start so quickly?
We all know that an engine's to...[Details]
System Principle
According to the average imbalance rate of the branch three-phase phase line load and the average value of the branch phase line current, the adjustment of the phase line load...[Details]
Abstract: This design uses field-effect transistors to create a tube-like audio power amplifier. The preamplifier uses a single Class A transistor, while the power stage utilizes Class AB push-pull...[Details]
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]
