Reducing CO2 emissions

Reducing (CO2) emissions

Escalating concern over rising carbon dioxide (CO2) emissions is driving worldwide demand for more pure electric vehicle and hybrid electric vehicles. While automotive has led this charge, the airline industry is ramping quickly and is analyzing the cost/performance benefits of electric-powered aviation. If air travel costs can be driven down, it can expand air travel to under-serviced or remote geographies.

A modular proven approach

A modular proven approach

The overall modularity and scalability of Vicor’s solution enabled Ampaire’s engineers to achieve key design advantages compared to bulky, conventional ‘silver box’ power supplies. These power technology advantages were complemented by Vicor’s proven heritage of providing military/aerospace-grade quality and reliability. In the highly regulated aviation technology domain, this helps streamline validation and certification cycles. This ease of component certification will prove to be a great asset as Ampaire transitions from its current modified hybrid powertrain architecture to a fully electric propulsion system.

2-stage modular solution

The power conversion and regulation is done in 2 stages, to optimize the efficiency and power density and to simplify thermal management.  A fixed ratio bus converter module (BCM) is used to isolate and down convert the high voltage battery, then followed by (stage 2) a low voltage DC-DC converter to regulate the output of the bus converter to 28V.
