Abstract :
The aim of this paper is to determine the different characteristics of a new power converter topology especially suitable for high voltage applications, called imbricated cells multilevel choppers (ICMC) in order to design the reactive components of this power converter, such the capacitors and the output filter. The characteristics of this power converter are calculated, plotted, and compared to those of an elementary chopper (current and voltage ripple, RMS currents, harmonic spectrum etc.). These characteristics are then used to design a 600V-25A three-level MOSFET chopper
