PWM Simulink Models — Half-Bridge, Unipolar, Bipolar
Three PWM variants as Simulink models, on one page — half-bridge, unipolar full-bridge, and bipolar full-bridge.
Bidirectional Single-Phase Inverter (Simulink Model)
A bidirectional single-phase inverter model — grid-connected, dq-frame current control, 4-quadrant operation.
A video walkthrough is available on YouTube.
What is in this model
- Plant: full-bridge inverter with four switches and an LCL output filter.
- PWM: sinusoidal PWM, bipolar or unipolar (switchable via parameter).
- SOGI: second-order generalised integrator for single-phase alpha-beta generation.
- PLL: synchronous-reference-frame PLL on the grid voltage.
- Current controller: decoupled PI in the dq frame.
- Grid: ideal voltage source.
