README
hardware/README.mdThis folder contains the KiCAD project files for the first PCB version. There are four schematic pages:
- Root page - top overview page. Displays how the individual sheets are connected, and contains some high-level elements such as mounting holes and input/output connectors;
- Control page - contains the MCU and precharge control elements;
- Power page - contains everything related to the high-power part of the inverter: the H-bridge, gate drivers, precharge relay, shunt resistors;
- Measure page - contains all circuits used for measuring voltages and currents: voltage deviders, amplifiers, offsets, filters.

Questions
How big is the Inv v1 PCB?
It measures 190 × 91 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Inv v1 use?
160 parts, built around the IR2113S, NE5532D, INA122U and LM1117MP-5.0/NOPB. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Inv v1 KiCad files?
From the reljamar/singlePhaseInverter repository on GitHub, at the commit this page was made from: the board is hardware/Inv_v1.kicad_pcb and its schematic hardware/INV_controler.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Inv v1 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
