Is there a learning development board for switching power supplies like a single-chip microcomputer? Otherwise, it seems difficult to get started. [Copy link]

Watching videos and reading materials, it feels dangerous to make a board yourself

PowerAnts did it back then, but it may not exist now. Texas Instruments did it once. You can check the official website of Texas Instruments and you may find it.

The above is a development board from Texas Instruments. Switching power supplies are indeed dangerous, especially high-power switching power supplies. If you don't handle it well, it will either smoke or explode.

There is a way to learn and toss. Go to an electric car repair shop, find a few electric car chargers, or buy a new one and disassemble it. Study it carefully. It is best to find which circuit board has UC3842. Check the typical circuit of the flyback topology switching power supply chip manual. Measure and study it carefully. It is best to use an oscilloscope.

It is best to get an appropriate sliding rheostat as a load, or use other loads, and pull it repeatedly. If you are worried about danger, if the laboratory has the conditions, use an isolation transformer and measure it casually.

Did you know that switching power supply engineers belong to the medium-risk industry? The proportion of work-related injury insurance premiums is higher than that of low-risk industries such as microcontroller development? It is defined as a learning board, which means it is for novices to use! In case of personal injury, can the person who sells the board afford the compensation?

The DEMO board that maychang posted on the 3rd floor is not dangerous. Generally, decent original manufacturers provide DEMO boards, which can be used for evaluation and learning.
