Impact of Capacitor Design Methodology on FC Inverters

Abstract

This work evaluates two capacitors design methodologies for Flying Capacitors Inverters. The first design methodology is developed through analysis of one switching period of the flying capacitor inverter. The second one analyses a complete output period of the inverter using the double Fourier series. Bolt methodologies use of the Phase-Shift Pulse Width Modulation. Experimental and numeric results verify the impacting of the two methodologies design in a five-level flying capacitor inverter.
