Frequently Asked Engineering Questions (FAQ)
What are the primary considerations for the gate drive design for the 1MBI600V-120?
For a high-power module like this, a well-designed gate drive is critical. We recommend a drive capable of sourcing and sinking at least 10-15A peak current to ensure fast, clean switching. Employing a negative gate voltage (e.g., -8V to -15V) during the off-state is highly advised to provide a strong noise margin against parasitic turn-on induced by high dv/dt. Furthermore, incorporating short-circuit protection (desaturation detection) is essential for system protection.
Can the 1MBI600V-120 modules be connected in parallel for higher current output?
Yes, paralleling these modules is a common practice. However, successful implementation requires careful design. Key factors include ensuring a symmetrical busbar layout to equalize stray inductances, using individual gate resistors for each module to prevent oscillations, and selecting modules with closely matched VCE(sat) characteristics to promote balanced current sharing.
