Comparison between innovative TO-247 IGBT copacked with SiC diode and SiC MOSFET in bidirectional boost converter

Bidirectional DC/DC converters are very useful in different sustainable energy sectors, such as renewable energies, and electric mobility. In the last application, automotive-grade power devices are required because of the high reliability requested to the system. Recently, the first automotive-grade TO-247 IGBT copacked with SiC diode has been manufactured. In this work its performance has been firstly investigated in a bidirectional boost converter. A comparison with SiC MOSFET has been also carried out in order to provide useful guidelines in the design of this converter.
