From the project
Open-source high-power 3-phase VSI with independent safety coprocessor, fully isolated gate drives, and node-based codegen configuration tools. Firmware, RTE, and telemetry live in OpenVVVF/RTE.
Our current in-progress build photos for size 2 are below, thanks again to our sponsors for helping make this possible
An open-source, high-power voltage-source inverter (VSI) for 3-phase AC drives. The design centres on a dual-MCU control board with an independent safety coprocessor, fully isolated gate drives and sensing, dual isolated CAN buses, and a control stack configurable through node-based codegen tools.
