A highly efficient 2kW 3-level full-MOSFET inverter
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.
期刊介绍：
The scope of the EPE Journal is to supply all experts in the field of power electronics and drives, with the most recent information on the rapid evolution in the field of power electronics, drives and industrial applications.
Alongside contributions from scientists, the Journal also wants to attract contributions from those who are designing and producing power electronics systems and those who are involved in the applications of those systems in industrial processes.
In addition to original research articles, information is supplied on new products, industrial developments, company portraits, the EPE Association as well as international organizations such as the European Commission.
The EPE Journal is recognized as a truly European specialized Journal on power electronics, drives and applications of a very high scientific and technological level. The Journal is in close relation with the bi-annual EPE Conference, the leading European Conference in the field, which brings manufacturers, researchers and users together.
