[i=s]This post was last edited by bigbat on 2019-1-8 11:39[/i] I have been using power modules from Jinshengyang and Meanwell for my projects, but they are too expensive. A 2W AC-DC output 5V, input 2...
Figure 3 is a waveform diagram of the entire echo, with sinusoidal echoes of different amplitudes at different locations. I want to determine the time of echo at different positions. The current idea ...
I recently got a TFT, the main control chip is ST7781R, and my screen uses SPI for data transmission.I have to say that this is not done using the SPI module, but by simulating the SPI using the IO po...
In 2006, the motor industry was greatly affected by the surge in raw material prices, but many companies minimized losses under pressure and achieved hard-won and gratifying results. Looking forward t...
They are freshmen (private college), the kind with very poor college entrance examination scores. Their school gave them Tong Shibai's Analog Electronics. The school is really nonsense. How can they o...
A line scan lens is an industrial lens used with line scan cameras. Its imaging principle is to capture the image of the workpiece using a linear sensor and then perform digital signal processing t...[Details]
A parallel inverter consists of two thyristors (T1 and T2), a capacitor, a center-tapped transformer, and an inductor. The thyristors provide a current path, while the inductor L maintains a consta...[Details]
To understand why car engines need gearboxes, we must first understand the characteristics of different types of engines. An engine refers to a machine that can convert a form of energy into kineti...[Details]

A multilevel inverter converts a DC signal into a multilevel staircase waveform. Instead of a straight positive-negative output waveform, the output waveform of a multilevel inverter alternates in ...[Details]
A pure sine wave inverter has a good output waveform with very low distortion, and its output waveform is essentially the same as the AC waveform of the mains power grid. In fact, the AC power prov...[Details]
Plug-in hybrid vehicles (PHEVs) utilize two powertrains. Their pure electric range is typically inferior to that of pure electric vehicles, often reaching less than half that. Currently, mainstream...[Details]
With the gradual popularization of new energy vehicles in recent years, more and more people have been able to access and purchase electric vehicles. The structure of electric vehicles is composed ...[Details]
