3.1 Digital realization of the MLI

Let's consider here the case of a three-phase voltage inverter whose control signals are generated by a PWM (pulse width modulation) process with carrier as shown in figure 8 . The aim of PWM control of a voltage inverter is to impose, at each carrier chopping period, an average voltage across each machine phase equal to its reference voltage. To achieve this objective, the reference voltages $V_{a o}^{*} (t), V_{b o}^{*} (t) et V_{c o}^{*} (t)$ ...
