BoF: Unlocking Software Defined Power Electronics with Zephyr: Concepts...
summary
Claims a working open stack: Zephyr plus custom drivers runs an OwnTech platform that controls a 300 W reprogrammable board (12–72 V low side, 40–110 V high side, 8 A per channel, 16 A parallel). Firmware uses an STM32G4 MCU with precise HR timers (about 13,000 timer steps at 200 kHz), custom ADC trigger and DMA paths, CAN + Thingset telemetry and an ESP32 uplink. Matlab auto-code generation and PlatformIO/VSCode workflow are integrated and the prototype runs; 30 test users so far do not destroy it.
