Innovative Full-GaN Inverter Development for 800V/100kW Automotive Applications

In the rapidly advancing field of EV applications, the design of high-efficient inverters is one of the key factors in improving overall vehicle performance. This paper presents the design of a three-level (3-L) automotive inverter based on GaN technology, aimed at enhancing the performance and efficiency of electric vehicles (EVs). GaN components, sourced from Cambridge GaN Devices (CGD), are utilized to leverage their superior switching characteristics and efficiency. The work is supported by both simulation and experimental results, which confirm the advantages of integrating GaN components and the 3-L inverter topology. The findings demonstrate improved performance, lower losses, and enhanced overall efficiency, making this design a promising solution for the future of EV power electronics.
