Description
<p>When the current was concentrated to the chip which was located on the far side from the sensor on the substrate, the sensor could not follow the rapid temperature risings and could not protect it.</p>
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.
