I said before that I would post a few articles about the experience of HelperA64 core board circuit design, but because of my single-threaded brain, I have never been in the mood to post. This time, I...
In order to reduce the impact of motor vehicles on the environment and meet the requirements of legislation related to fuel economy and carbon dioxide emissions, the promotion of hybrid and electric v...
[img=960,381]http://cache.amobbs.com/new2012/forum/201406/21/165722hz6axbmb3q2tb2az.jpg[/img] The PIC12F508 microcontroller has no interrupts, and the timer and key interrupts can only be queried. The...
The signal generator outputs two 10KHZ sine wave signals at the same time, which are added to the channel 0 and channel 2 of the single-chip microcomputer (MCU uses STM32F030C8T6) and collected altern...
This paper introduces the control principle, technical features and software flow of industrial control computers in high-voltage reactive power automatic compensation. It also elaborates on the reali...
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]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]

1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
The TPS92210 is a single-stage LED lighting pulse width modulation (PWM) controller. The TRIAC dimmable solution not only regulates the LED current, but also achieves a power factor close to 1. The...[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]
Introduction
In industrial control, speed measurement is often required. Generally, a contact tachometer is used. This tachometer must be placed against the center of the shaft to measure. It...[Details]
Car lights, whether headlights, fog lights or tail lights, play an important role in driving safety. However, the material of the car lights determines that the probability of damage in a collision...[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]
