PHiVe will demonstrate one of the essential power electronic systems required for a hybrid electric propulsion system, ensuring that they are reliable and of minimal size / weight.  The project will deliver impacts in the four areas that the Clean Sky programme seeks to support:


PhiVe will deliver a paradigm shift in power conversion technologies operating at voltages greater than 2kV, at frequencies of greater than 10kHz and in altitudes of higher than 30,000 feet, which translates to low temperatures and low atmospheric pressure. It will provide a clear understanding of the challenges of moving to higher voltages, opportunities to maximise performance in design and knowledge about the methods that will be used to test and qualify such systems for use on board modern aircraft.

Environmental Impact

PhiVe will deliver power conversion technologies that will form a key component in the hyrbid propulsion system of the future, delivering CO2 savings of 25-35% compared to today’s technologies. The project will also seek to minimise the mass and weight of the power electronic system providing further incremental benefits in performance.

Industrial Leadership

PhiVe brings together key european scientific experts and companies who can collectively exploit these technologies. These power conversion technologies will be able to cope with the stress of operating in harsh environments and will be applicable to a wide range of industrial sectors. Consortium members are engaged in standardisation activities that are an essential part of the pathway to taking a new technology from demonstrator to product.

Enhanced Mobility

PhiVe will contribute to the opening of new business models and new routes as hybrid aircraft will require less fuel and hence, will be able to operate from airports that do not have the capacity to service high fuel demand.

The project team consists of a group of members from across Europe and the project has received funding from the Clean Sky Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme.
