  Smart Solution for 1500VDC 3-Level Central PV Inverters

  In general a problem occurs when 3-level NPC topologies are developed using several standard half bridge power modules. A series connection of IGBT modules results in high stray inductances which in combination with high switching di/dt cause high switching overvoltages [2]. IGBT modules with an integrated NPC topology phase-leg containing 4 IGBT and 6 diodes potentially have lower stray inductances but are not available for high current ratings and are more expensive due to the complex...
