Hello everyone, this is my first official blog. As people in the micro-era, we no longer have time to read lengthy blog posts. But when it comes to learning, there must be a process of accumulation. S...
[size=3]The following summarizes the basic principles and parameter design references of switching power supplies[/size] [b]1. Circuit composition of switching power supplies[/b] The main circuit of t...
I am working on a project that requires amplifying and processing the light signal received by the photoelectric sensor and finally converting it into a numerical value on the display screen. I don't ...
In VHDL, parameters can be defined in generic statements. Generally, the bit width is defined here, and other parameters can be defined in the package. We will not discuss this here. A very good state...
Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[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]
The data collector of the automatic weather station is generally designed based on a single-chip microcomputer or a PC/104 bus controller. It has the characteristics of good compatibility with PC, low...[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]
At present, how various communication technologies will evolve after 3G is a focus of great concern in the industry. Especially for TD-SCDMA, whether it can achieve smooth evolution to the next gen...[Details]
The above is to use MB1404 as a stereo composite signal transmitter. You can use the internal high-frequency amplifier and oscillator or not! According to my experience, I still recommend beginners...[Details]
Cars equipped with xenon headlights are already common on the road. Whether they are standard equipment on high-end cars or embellishments on modified cars, xenon lamps are gradually becoming a sym...[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]
In order to prevent the lithium battery from being damaged by abnormal conditions such as overcharge, over discharge, and overcurrent, a lithium battery protection device is usually used to prevent...[Details]
Rated capacity refers to the maximum output power of the UPS (the product of voltage V and current A).
