(about 22 A). This is due to the SiC capacitance discharge at high di/dt = 1400 A/µs. The

step on the drain voltage (trace in red) is due to parasitic inductance of the board. The violet

trace represents the energy losses during turn-on. Turn-off is performed with a signal diode

connected in parallel to the 8.2

order to obtain the fastest commutation speed. All measurements have bean performed on

a grid-connected 3 kW solar inverter prototype, totally equipped with both MDmesh™ and

SiC devices.
