Redefining the sources of power

The Design Engineer’s Guide to Power Conversion in eVTOLs: Why Reliability is Critical and How Modular Architectures Can Help

Electric Vertical Take-Off and Land (eVTOL) vehicles are set to proliferate in the coming few years. As in other aerospace applications, safety is paramount, normally requiring multiple layers of hardware redundancy. eVTOL craft however must be as lightweight as possible, so a trade-off has to be made between acceptable reliability and hardware complexity. This e-guide considers the situation, particularly with regards to power conversion electronics.

DC-DC Conversion for Auxiliary Power in Hi-Rel Military Vetronics Applications

Increasingly, military vehicles are provisioned with electronics for control, communications, navigation and display systems. DC-DC converters provide auxiliary power for these systems but can be subject to high electrical and environmental stress in the application. This article outlines the stress levels defined by the common standards used and identifies the specifications that DC-DC converters need to meet.
