The benefits are the negligible small diode losses of the SiC diodes. In the following two comparative examples are given for an all-silicon device and a hybrid device with 1200V/300A rating.
(1) If both modules have a fixed output current Io=212Arms and the switching frequency of the hybrid module is raised to 1.5 times of the all-silicon one, they still have similar losses.
(2) If both modules have a fixed switching frequency fsw=16kHz and the output current of the hybrid module is raised to 1.2 times of the all-silicon device, they still have similar losses.
