PWM Three-Phase Inverters Design in MATLAB a 3-phase inverter as shown in Figure below with PWM Generator. The 3-phase inverter has 6 switches controlled by with PWM as shown in figure below. Note that S₁, S3, and S4 are generated from PWM Generator and S4, S6, and S₂ are their complementary signals respectively. (Note, your should design your own PWM). In order to generate a three-phase sinusoidal waveform (AC) at the inverter output, we must consider three reference signals that will be compared to a carrier signal. As the case for 3 phase signals, reference signals should have 120° (2 rad) between each other. The inverter and PWM have the following parameters: Vdc =100, f-60, R=10, L-20 mH, and the modulation index used for each phase m₂=0.7 and m-9.
