Description
Monitor collector current of every IGBT, and protect against overcurrent by cutting off the current Protects against short circuit current by cutting off the current by the same means as overcurrent protection
When the current was concentrated to the chip which was located on the far side from the
Features
- of Fuji Electric’s IGBTIPMs and the R-IPM are introduced in the following. 2. Fuji Electric’s Conventional IGBT-IPM Line-Up and Problems
The line-up, performances and features of both the J-IPM and N-IPM are shown in Table 1. The J-IPM was developed with particular attention to low loss. The N-IPM realized low noise (soft switching) and low loss in order to respond to the market needs of EMC (electro magnetic compatibility) regulations and to match the CE mark. Furthermore, the N-IPM is an IPM.
