Mr. Lei talked about the comprehensive upgrade of electronics: the project update time is once every 4 months, and each time the project is fully stressed tested, thermal test, derating test and other reliability tests, and all components can be purchased on Taobao to ensure that everyone can reproduce and operate stably and reliably.
Bilibili search Mr. Lei said that the complete calculation data can be downloaded electronically, and this project can be contacted by commercial authorization.

Precautions
This project involves high voltage, safety first, do not touch the capacitor with your hands.
When the output of 1000W power requires a fan to strengthen heat dissipation, it must be ensured that the heat dissipation is good before it can run at full power to prevent overheating.
The debugging process must be understood on Bilibili before powering on. There is a full set of tutorials in Bilibililei to teach electronics.
