Abstract
This work presents an EMC modeling in conducted mode of a serial chopper designed for a photovoltaic application. Indeed, the frequency rise in semiconductor materials and the very short switching time of the switches promote electromagnetic interference and coupling with neighbouring environments. In order to overcome its drawbacks, effective methods have been adopted to reduce electromagnetic noise levels, such as Random Pulse Width Modulation (RPWM), which allows the electromagnetic spectrum to be spread over a wide range of frequencies, and the use of soft switching.
