EMI suppression for single-phase grid-connected inverter based on chaotic SPWM control

Abstract

Ahstract-This paper is to design a novel chaotic sinusoidal pulse width modulation (SPWM) for grid-connected inverters, which has the advantages in design flexibilities and low costs, for reducing electromagnetic interference (EMI). Furthermore, the proposed chaotic SPWM can also be used to improve the total harmonic distortions (THD) of grid-connected currents without excessive harmonics. Here, a chaotic carrier is the key to realize the chaotic SPWM control. Finally, simulation and experimental results are given to show the validity of the chaotic SPWM in reducing EMI.

Effective Suppression of Conducted Electro Magnetic Interference in DC-DC Boost Converter Using Field Programmable Gate Array Based Chaotic Pulse Width Modulation Switching

“…Thus, it can be concluded that the proposed scheme can be used for attaining EMC where conducted noise reduction attained is less than 4 dB. In addition, the proposed scheme reduces the size of the EMI filter required [22][23][24].…”
