Research on discrete IGBT7 H7 1200 V in inverter for Solar and UPS applications

Inhalt:
This paper presents the research results on the newly introduced Infineon TRENCHSTOP(TM) IGBT7 H7 1200 V technology, including the performance evaluation and comparison with predecessor 1200 V H3, CS6 IGBT based on doing double pulse test, and also giving the system benefits by simulation under application conditions. Thanks to the latest Micro-Pattern Trench technology and thereafter dramatic switching losses and conduction losses reduction, Infineon IGBT7 H7 1200 V is the most promising candidate to address the high switching applications like Solar and UPS inverters, which are more caring about efficiency improvement and system power density increasement.
