Downscaled Inverters
About the Downscaled Inverters PCB
Downscaled Inverters is an open source PCB design by Bausager, published on GitHub. It is a 2-layer board measuring 139.7 × 116.8 mm, with 111 components from 19 distinct parts.
Other key parts include the NUCLEO-F446RE, INA181 and MCP6004. By type, the board carries 37 resistors, 34 capacitors, 15 inductors, 9 transistors, 9 diodes and 5 ICs.
From the project
Downscaled three-phase half-bridge inverter
This is an accumulative project, this means it's going to improve over time. There's a limited number of people working on this which means updates somethimes takes sometime. If you want to help improve, collaborate or have something in your back pocket you want to integrate, you are very welcome to contact me! The more the merrier!
There're some restrictions! Since this is an open-source, student use it and research need to be understood and replicated, the code needs to be written in such a way that other prople can understand it. Even if the person isn't an expert. That is importent!
