Inhalt:
The objective of connecting a MOSFET and an IGBT in parallel is to combine the advantages of both semiconductor technologies. Such hybrid switches have been investigated in a high frequency test setup for resonant converters. These converters are commonly used in high voltage generators (e.g. for medical applications). In this paper three MOSFETs connected in parallel are replaced by a single hybrid switch. For this, a corresponding super-junction MOSFET has been combined with different IGBTs from several manufacturers. The performance of these hybrid switches has been analyzed by efficiency measurements within the test setup for different operating points.
