| Abstract |
E-mobility faces an increasing need to enhance the performance of electric vehicles (EV). In this context, a project is underway to develop an 800V inverter with high power density. This article focuses on the development of a new DC-Link system, including laminated bus bars, capacitors, and cooling components. The main challenge was meeting capacitance and inductance requirements, within limited volume and thermal limitations of assembled components. This development has resulted in characterized prototypes, validating the results obtained from preliminary simulations. Optimized thermal management ensures the DC-Link temperature is controlled, guaranteeing capacitors lifespan up to 40,000h for an inverter with a nominal voltage up to 900V. This work also includes the Life Cycle Assessment (LCA) of the product, showing that 96\% of the greenhouse gases emitted by the product are produced during its operating phase. |
