Inhalt:
There is a trend to 1500V open circuit (OC) voltage systems in solar applications. Efficiency, cost and small footprints are all highly relevant value propositions for solar inverters. Reducing the number of paralleled IGBT power modules is key to achieve a small footprint and to reduce the cost. Selecting the right topology can decrease the size of the filter by increasing the switching frequency. In this paper an IGBT power module for three-level topologies is presented. This module reduces the number of paralleled modules. Further the benefits of different Neutral Point Clamped topologies (NPC) and direct water cooling systems are being discussed.
