Electrical Power Distribution Boxes for small aircraft

The EPDB is a set of two Electrical Power Distribution Boxes (EPDB) intended for small utility/commuter aircraft of the CS-23category, powered with two engines from a 28 Vdc electrical power system. EPDB's main function consists in the intelligent management of electrical energy, thus ensuring the distribution of the power from airborne electrical sources to airborne electrical loads. This paper deals with the concept design of the EPDB, describes the basic architecture and considers the regulation aspects.
