Power Modules simplify inverter design

July 22, 2014 // By Christoph Hammerschmidt
Mitsubishi has expanded the lineup of its J1 power modules for electric and hybrid vehicles. The new models feature the same package as other J1 series models, thus simplifying the design of capacity inverters.

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.
