Hello

Can we use the SiC Power module along with the Three-Phase Motherboard like MOD-MB-3P-0900V-40A-N for DC-AC (inverter) and MPPT design to use all in one? Can yo

Coardilly,
Biruk

    Hello biruka,

    Can you please provide more information? Which power module would you like to use with MOD-MB-3P-0900V-40A-N? What is your system current and voltage requirements?

    Which MPPT design are you referring to? Thanks!

    Hello,

    Thanks for your reply. I am just looking for SiC power modules suitable for up to a 10 kW to 50 kW inverter.
    Our system operates at 400VDC with a maximum current of 200A. We are considering a centralized MPPT design with incremental conductance as the control algorithm for a 10 kW to 50 kW inverter.

    For the power module, we have not decided yet because we did not make sure which power modules are compatible with MOD-MB-3P-0900V-40A-N motherboard. However, I am thinking about CCB032M12FM3, and CAB450M12XM3.

    Hello Biruka,

    Thank you! For a DC bus of 400V, you can also consider 650V rated devices from our discrete device portfolio. We have many compatible daughters cards for 650V devices to choose from for MOD-MB-3P-0900V-40A-N.

    However, the limitation with using  MOD-MB-3P-0900V-40A-N is it cannot support 200A. You can use the design for a proof-of-concept at lower power. The maximum continuous RMS current rating for the DC bus and switch node terminals is 40 A.

    There is no plan to develop a daughter card for CAB450M12XM3 compatible with MOD-MB-3P-0900V-40A-N as the mother board is unable to support the current rating of CAB450M12XM3 .
