The GD32F4 series is the earliest M4F core MCU I know of in China. Several other series such as F3 and E1 are M4 cores without h...
In 2013, wearable smart devices became popular. In addition to smart watches, smart glasses and other smart phone assistants, health monitoring tools such as the Jawbone Up wristband seem to be more p...
I wonder if there is a minimum system schematic diagram of the TM4c123gh6pm microcontroller in the forum - using the TI experimental board, but I can't find it....
I made three 6748 boards of my own. Board_A can work normally and can enter debug mode from CCS. However, board_B and board_C cannot enter debug mode in CCS. As shown in the figure below:You can see t...
In any switching power supply design, the physical design of the PCB board is the last link. If the design method is not appropriate, the PCB may radiate too much electromagnetic interference, causing...
My focus is on the boost DC-DC converter. All modeling work is for boost, but the conclusion is suitable for buck and buck-boost (everyone is welcome to verify). When it comes to small signal modeling...
At present, the development of wireless power supply technology for electric vehicles (EVs) is becoming more and more active. In 2012, Volvo of Sweden established Volvo Technology Japan in Tokyo as...[Details]
Automotive applications are particularly sensitive to EMI events, which are unavoidable in a noisy electrical environment consisting of a central battery, bundled wiring harnesses, various inductiv...[Details]
In order to highlight the concept of "energy saving and environmental protection" of intelligent buildings, solar street lights are designed for intelligent communities. The inclination and capacit...[Details]
In public places such as schools, government agencies, factories and mines, as well as public corridors in residential areas, the phenomenon of long-burning lights is very common, which causes a h...[Details]
In recent years, lighting has become an important area that countries around the world are targeting to promote energy conservation and environmental protection. According to statistics, about 20% ...[Details]
Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
Since the late 1990s, with the demand for higher system efficiency and lower power consumption, the technological update of telecommunications and data communication equipment has promoted the deve...[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]
Rated capacity refers to the maximum output power of the UPS (the product of voltage V and current A).
Usually, the UPS power supplies sold on the market are marked with "W" (watt) for smaller...[Details]
