Abstract
In this paper, we present a power conversion solution used to integrate batteries and fuel cells for E-VTOL aircraft. The power converter needs to be designed to handle wide input and output voltage ranges to meet the operating requirements of the fuel cell and battery. Additionally, high efficiency, light weight, and electromagnetic compatibility are critical for power converters used in E-VTOL aircraft. In high-voltage, relatively low-current applications (such as a sub-module of a high-current design), hard switching operations are less ideal because they produce significant switching losses and EMI noise. A solution to achieve high efficiency, light weight, and lower EMI is to deploy a soft switching operation. We propose a multilevel power conversion solution that can achieve soft switching for E-VOTL power converters and explore the optimal design strategy. We have built and tested an experimental prototype to prove the concept.
