ROHM’s TRCDRIVE pack for significantly smaller xEV inverters
The rapid transition to climate-neutral and energy-efficient means of transportation makes an important contribution to a greener future. The development of more compact, efficient and lighter electric drives plays a crucial role in promoting the spread of next-generation electric vehicles (xEVs) and achieving environmental goals such as carbon neutrality. The improved efficiency of the drive converter is particularly critical for electric vehicles in order to increase the range and reduce the size of the on-board battery.
SiC as key components of electromobility
Silicon carbide (SiC) will undoubtedly play a major role in this development. However, it is a major challenge for SiC power components to achieve low losses while maintaining a small size. ROHM solves this dilemma with its TRCDRIVE pack, a series of SiC modules specifically designed for traction inverter applications, reducing their size through a unique structure to maximize heat dissipation area. The integration of ROHM’s 4th generation SiC MOSFETs with low on-resistance results in an industry-leading power density that is 1.5 times higher than conventional SiC modules. At the same time, it contributes significantly to the miniaturization of inverters for xEVs.
Unique configuration
TRCDRIVE pack supports up to 300kW and features high power density and a unique terminal configuration: So the modules help to solve the key challenges of traction inverters in terms of miniaturization, higher efficiency, and fewer person-hours.
The modules are also equipped with control signal terminals using press fit pins enabling easy connection by simply pushing the gate driver board from the top, reducing installation time considerably. In addition, low inductance (5.7nH) is achieved by maximizing the current path and utilizing a two-layer bus-bar structure for the main wiring, contributing to lower losses during switching.
