High power density SiC power module for Formula E: requirement, design considerations and the test results

Formula E: Requirements, design considerations and test results of high power density SiC power modules.

Due to its competitive nature Formula E requires fully optimized power converters with semiconductor modules having best possible efficiency levels and latest device and packaging technology. In the article below the key requirements of Formula E vehicles are written down and compared to solutions used in standard electric vehicles. In the next stage the different design options are taken into consideration such as semiconductor device selection, power density, thermal resistance and module integration. After all design choices are made, the specifications and capabilities of RoadPak modules are determined for utilization in Formula E power inverters. Well-designed inverter in addition to high energy-efficiency can allow Formula E vehicle to go into the attack mode, granting additional power on the motor which will give an edge during takeovers or strategic maneuvers.
