3 Phase SPWM Rectifier

Three phase rectifier, with sinusoidal Pulse width modulation. (3 leg MOSFET based)

You are now following this Submission

Three phase rectifier open loop operation demonstrated. 3 Leg converter use SPWM to produce DC output.

Features:
- Ability to control output dc voltage by varying the modulation index
- Optional feature to inject 3rd Harmonic Injection if required.
- Automated post simulation plots to demonstrate input & out voltages.
