Abstract :
This paper investigates an improved 3-level flying capacitor inverter topology allowing a drastic reduction of reverse recovery related losses. It benefits from the latest superjunction (SJ) MOSFET devices. The presented 2kW inverter was designed for Japanese PV market (200Vrms). It allows non unitary power factor operations with peak and European efficiency of 98.0% and 97.6% respectively. Thanks to SJ MOSFET implementation, it outperforms state-of-art configuration using IGBTs and SiC diodes in terms of efficiency.
