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.
PWM Strategies for Full-Bridge Inverter (PDF)
A PDF that compares three PWM strategies for the full-bridge inverter — bipolar, unipolar standard, and unipolar fast-slow.
A video walkthrough is available on YouTube.
What is in this PDF
- Bipolar PWM: single carrier, inverse gate logic, two-level output.
- Unipolar PWM (standard): two carriers, two modulators, three-level output.
- Fast-slow unipolar PWM: one leg at the switching frequency, the other at the line frequency, three-level output.
- Each variant includes: gate-logic diagram, output-voltage Fourier series, harmonic spectrum, switching-loss estimate, and inductor-sizing implications.
- Python notebook with the numerical examples
