Abstract:
This paper describes a demonstration of the low loss performance of a 6.5 kV innovative silicon power device (i-Si) module. The i-Si module uses stored carrier control to both the switching device and free wheel diode, which is made entirely from silicon. A 6.5 kV 800 A i-Si module was fabricated at a size of 130 mm × 140 mm. Despite having a package size 2/3 that of a conventional 6.5 kV 750 A IGBT, the fabricated i-Si module has 40% lower loss, similar to that of SiC MOSFETs.
