# Three-Phase Grid Inverter

## Overview

Use this active subskill for three-phase grid-connected inverter work. It contains the populated knowledge in this repository: T-type/NPC three-level SVPWM, state-vector table checks, gate mapping, From/Goto routing risks, and simulation-backed waveform validation.

Use the root `simulink-power-electronics` workflow first, then load this subskill when the model is in scope.

## Resource Map

- Read `references/svpwm-three-level.md` for T-type or NPC three-level SVPWM logic, sector handling, and gate mapping.
- Read `references/table7-state-vectors.md` when auditing or rebuilding the 36 small-sector state-vector table.
- Read `references/vsg-control-notes.md` for VSG (Virtual Synchronous Generator) control implementation, PI tuning experience, power calculation verification, and feedforward formulas specific to grid-connected inverters.
- Use `scripts/svpwm_diagnostics.m` when MATLAB/Simulink can run and the model exposes state, gate, and voltage signals.
