3-Level IGBT Module

Compared to the 2 level modules, the 3 level modules enable a output waveform which closer resembles a sine wave. Therefore, the LC filter can be reduced in size. Further, the switching losses can be significantly reduced, which is useful for highly efficient designs. 3 level modules are suitable for wind and photovoltaic power generation systems, and uninterruptible power supply systems.
Fuji Electric provides IGBT modules compatible with both T-type and I-type 3-level circuits. Fuji Electric’s uniquely developed RB-IGBT (Reverse Blocking) chip is used for the AC switch on T-type modules to realize very low conduction losses.
