Abstract
This paper deals with a three-level inverter topology
in the 3 kW range as an alternative to commonly used three-level
topologies. The topology is attractive for having low switching
losses due to the utilization of CoolMos switching devices while
keeping conduction losses low due to the utilization of IGBTs.
A proper time delay between the CoolMos and IGBT devices
increases the efficiency by 0.2%. Maximum efficiencies of 97.7 %
are achieved and less than 0.2 % efficiency degradation is possible
with doubled switching frequency. The case temperatures of the
switching devices are below 60 ◦C at full power
