It takes 8-10 hours to charge a car, which is tantamount to treating the charging station as a parking lot. So we can think about it in another direction: Can the parking lot also be used as a chargin...
I want to make a button for long pressing to shut down the system in WinCE5.0. The hardware is connected to the interrupt, but I don't know how to handle it in software. If it is just a simple stream ...
ABB550 series inverter, the motor is 37KW made by a small factory (not a variable frequency motor). The interference cannot be removed. The inverter has a separate power distribution cabinet, and the ...
I used the three-wire mode. After the host was running, the SCK corner had not been output. I used the UTR0 and SPI0 of 360. So when designing the pins, I skipped P0.1, P0.2, and P0.3 as a test port. ...
I found that this reset circuit can download the program, but it cannot be started. After pulling up a 10K resistor on NRST_MCU, it can work normally. Can you please discuss why this is? Thank you!...
The program was originally compiled under QT and ported here. The normal code under QT is as follows: #define OUTPUT_DEBUG_INFO //Input debugging information to the terminal #ifdef OUTPUT_DEBUG_INFO #...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]

I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
With the development and widespread application of computer technology, especially in the field of industrial control, computer communication is particularly important. Although serial communication g...[Details]
Overview
In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[Details]
LED guardrail lights use fluorescent tubes or LEDs as light sources and continuous guardrails as carriers to form an approximately linear guardrail light strip. This article mainly introduces...[Details]
Since AC mains power may experience power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations during supply, these factors will affect the continuous ...[Details]
Fruit planting is an important part of China's agricultural development, and fruit tree pest control operations are becoming more and more important. At present, the overall level of pesticide applica...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
There are many types and styles of digital voltmeters in design and development. Traditional digital voltmeters have their own characteristics. They are suitable for manual measurement on site. Tra...[Details]
