This simulink file mainly contains 3 parts: 1. Simulate the traditional SVPWM modulation three-phase two-level inverter, build the SVPWM modulation module step by step, including coordinate transformation, synthetic voltage vector sector judgment, and basic voltage vector action time calculation , Trigger pulse generation, etc. 2. Simulate the SAPWM modulated three-phase two-level inverter, that is, by injecting the third harmonic into the three-phase modulation wave to obtain the effect equivalent to the traditional SAPWM, thereby simplifying the simulation process. 3. Use simulink's built-in SVPWM module and built-in three-phase circuit module to simulate the above circuit. The version of this document is version 2018b.
