The Operating Improvement of the Supply Source and the Optimization of PWM Control

Farouk Hadj Benali, Fouad Azzouz, Ghalem Bachir


In this paper the operating improvement of the supply source and the optimization of PWM control are proposed. A comparison (based on the better operating in terms of input voltage) between the multilevel inverters (NPC multilevel inverter and H bridge inverter) is studied. Then two control strategies (the SPWM and the suboptimal PWM) are applied to the multilevel inverter which has the better voltage performance. At last a comparison between these two control techniques based on two essential points, the THD and the output voltage value. A comparison between our results and results taken from literature is also presented in this paper. Simulations are carried out using PSIM environment.
