Frequently Asked Questions (FAQ)
What is the primary benefit of the module's low inductance structure?
The low inductance design minimizes voltage overshoots and ringing during high-speed switching events. This allows for faster, more efficient operation, reduces switching losses, and can simplify the design of external Snubber Circuit s, ultimately improving overall inverter reliability.
How does the 2080W power dissipation rating impact system design?
A high power dissipation rating indicates superior thermal transfer from the IGBT chips to the heatsink. For a system designer, this translates to more effective cooling, allowing the module to operate reliably under high continuous current. It provides a larger thermal margin, which can lead to a more compact heatsink design or higher power density for the overall system.
