Figure 24. Example of power supply configuration
2.3.2 Driver section
The driving section configuration is related to the power switch technology. In this case, we considered the SiC
power MOSFETs. The figure below shows this specific configuration.

2.4 Preliminary test procedure
2.4.1 AC sensing
To verify the proper operation of the AC sensing ( Figure 26 ), analyze the test points for voltages ( Figure 27 ) and
currents ( Figure 28 ).
