The devices are designed for 300A / 1.200V and for 300A / 650V. The 1.200V model is suited to high-voltage battery inverters as used in hybrid buses and trucks, while the 650V module aims at small-capacity inverters for small electric vehicles and mild hybrids.
The J1-series lineup is being expanded to meet the requirements of high power supply voltages and small-capacity inverters. The new products meet the demand of EV/HEV inverters in compact and large vehicle, not just mid-sized models.
This series features an extra-compact 6-in-1 package which shrinks the inverter footprint to about 80% of three 2-in-1 J-series T-PMs. The seventh-generation CSTBT semiconductor technology used for the modules enables collector-emitter saturation voltage to be reduced by abut 15%. Direct cooling package with cooling fin improves heat radiation by about 40%, again compared to 2-in-1 J-series T-PMs.
The modules will be exhibited at the Motortech Japan 2014 trade fair from July 23 to 25. The company added that it plans to ship samples on October 31.
