Dear Friends,

Silicon carbide will help establish electromobility by contributing to higher efficiency and thus greater range per charge. Range is still one of the most frequently cited reasons against e-vehicles.

Find all my magazines from 2006 on in our free archive on bodospower.com. There is no better way to communicate. We all share one world. As a publisher I serve the world: one magazine, on time, every time.

Best regards,

RoadPak

Superior power cycling capability for e-Mobility applications

The rapidly increasing interest in e-Mobility is driving sales of electric cars, buses and trucks in many countries worldwide. An important factor for the sustainable long-term success of e-Mobility is power semiconductors that are reliable in harsh and demanding environments.

Figure 1: RoadPak

Hitachi Energy’s RoadPak is the latest generation high-power SiC power module designed specifically for e-Mobility applications. It has been proven to deliver the full benefit of SiC technology and offers the long lifetime required of an e-Mobility converter, even in harsh conditions.

Power cycling test results¹ show that RoadPak meets all operational requirements over the full lifetime of the product. A detailed model is also available that supports lifetime analysis.

The test results also clearly show that, by using enhanced packaging technologies, superior power cycling and chip reliability are achieved, as the failure mode will be shifted back to the chip metallization or the chip thermo-mechanical degradation
