How a 3-Phase Inverter Works (Deadbeat Control)
A simple 3-phase inverter using a deadbeat controller in abc coordinates.
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.
A video walkthrough is available on YouTube.
What is in this model
- Plant: 3-phase inverter with six switches, a three-phase inductor, and a grid voltage source.
- Clarke and Park transforms: abc to alpha-beta to dq.
- PLL: synchronous-reference-frame PLL locked on the grid voltage.
- Current controller: decoupled PI in the dq frame with feed-forward compensation.
- PWM: inverse Park and inverse Clarke transforms back to switch gates.
