•
Follow the mounting procedure as explained in section 3.8 of the manual and mount the heatsink if required accordingly
•
Supply 15~18V at the connector CO1 to power the board
•
Set the pulses for HS_PWM and LS_PWM with required switching frequency, pulse width and deadtime as necessary.
Connect accordingly at the connector CO2 or use the BNC connector
•
Choose the input capacitor, output capacitor and inductor as per requirement. Check the connections of input, output
capacitors, inductor and load for each of the topologies as shown in Figures 12, 13 and 14
•
Set the required input voltage and adjust/increase the load slowly as required by keeping an eye on the case temperature
of the SiC MOSFET
Figure 17 shows the efficiency measurements in buck operation of SiC MOSFETs SCT4036KW7 and SCT4062KW7 with this
evaluation board.
