From the project
Projeto de um Inversor Trifásico com Controlo Digital assente num STM32H755. Implementa modulação SPWM a 25 kHz, controlo escalar V/f e um Retificador Monofásico Ativo (AFE) com fator de potência unitário. Desenvolvido no GEPE - Universidade do Minho.
O objetivo principal deste sistema é ultrapassar as limitações dos sistemas de controlo analógico (como a suscetibilidade ao ruído e restrições na precisão), transferindo a lógica de comutação e modulação para o domínio digital através de um microcontrolador STM32 NUCLEO-H755ZI-Q.
Projeto desenvolvido com o apoio do GEPE (Grupo de Eletrónica de Potência e Energia) e do NEEEICUM (Núcleo de Estudantes de Engenharia Eletrónica Industrial e Computadores) da Universidade do Minho, Guimarães.

Inverter Digi: common questions
What microcontroller does the Inverter Digi use?
The Inverter Digi is built around the ST_Morpho_and_Zio_Connectors_144_STLink, from the STM32 family.
How big is the Inverter Digi PCB?
The Inverter Digi measures 379.1 × 174.6 mm, has 4 copper layers and is 1.6 mm thick.

209 components, from 56 distinct parts. The full bill of materials is listed on this page.
Where can I download the Inverter Digi design files?
From the SlenderN679/Inversor-trifasico-digital repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Inverter Digi design in my own project?
The repository has no license, so all rights stay with SlenderN679. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Inverter Digi without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
