Abstract
An electrical vertical take-off and landing (eVTOL) aircraft includes a plurality of electrical propulsion units (EPUs), each EPU having a propeller or a fan configured to be driven to rotate by an electrical motor arranged to receive electrical power from a respective power electronics converter. Each power electronics converter includes a converter commutation cell having a power circuit and a gate driver circuit, the power circuit including at least one power semiconductor switching element and at least one capacitor. At least one terminal of each power conducting switching element is connected to at least one electrically conductive layer of a multi-layer planar carrier substrate at an electrical connection side of a power semiconductor prepackage, which includes at least one electrically conductive layer located on an opposite side of the power semiconductor switching element to the electrical connection side of the power semiconductor prepackage.
