Baseplate
(faster switching) will result in lower PDIV. This is largely
because that shorter rise time will have more impact on
the voltage integration over time when the applied voltage
pulses are short.
The decreasing PDIV with fast switching speed means
more challenges in the insulation
design of SiC and GaN power modules,
especially for aerospace applications
where there is a need to further
reduce footprints of baseplates for
power modules for weight reduction
purposes.
For future hybrid and turbo electric
propulsion, the required electric
power is estimated to be 20 MW for
a commercial regional single aisle
aircraft. This means that the dc distribution
voltage for these aircrafts
will need be much higher than current ±270 V. Thus, the
expected high voltage, together with the high altitude and
high switching speed call for innovations in insulation
material, insulation design and grounding strategies.
EMI
At cryogenic
temperature, some
devices showed
decreased switching
losses while some
showed increased
switching losses.

The higher switching speed and
higher switching frequency of WBG
devices will improve the efficiency
and power quality of power electronics
circuits. But at the same time,
more EMI related issues could be
expected. For motor drives, as shown
in Figure 7, the common mode current
largely is a result of the common
mode voltage at the neutral point of
the electric machine and distributed
parasitic capacitance of the motor,
