3-Phase Inverter in dq-frame (with PLL and Current Control)
A 3-phase inverter in dq-coordinates: Clarke + Park transforms, a PLL for grid synchronisation, and a decoupled PI current controller.
How a 3-Phase Inverter Works (Deadbeat Control)
A simple 3-phase inverter using a deadbeat controller in abc coordinates.
A video walkthrough is available on YouTube.
What is in this model
- Plant: 3-phase inverter with six switches, three inductors, and three output capacitors.
- Controller: deadbeat controller in abc coordinates — solves for the duty cycle directly from the current-tracking requirement.
- Grid: ideal 3-phase voltage source.
- Scopes: abc currents, abc voltages, duty-cycle commands.
