Abstract :
This paper firstly use the chaotic space vector pulse width modulation (SVPWM) control to improve the EMI characteristic of photovoltaic (PV) inverters. According to the operating principle of chaotic SVPWM control, it has the advantages in low costs, simple design and suppressing EMI without EMI filter, the implementation method of the chaotic SVPWM control is following provided. Furthermore, the chaotic SVPWM is also employed to improve the total harmonic distortions (THD) of PV inverters, where, a chaotic carrier plays a key part in implementing the chaotic SVPWM control. Finally, simulation results of a PV inverter with different output inductance are given to validate the effectiveness of the chaotic SVPWM in suppressing EMI and improving THD.
