Abstract: An electrical architecture for an aircraft having a primary three-phase electrical network powering a transformer-rectifier unit serving to power two secondary DC electrical networks. Each of the two secondary electrical networks includes a contactor electrically connected to a generator-starter. The contactors are linked in pairs to prevent them from being closed simultaneously. The second secondary network powers the generator-starter to start a fuel-burning engine. The first secondary network can be powered by the generator-starter to power electrical components. A secondary voltage of the second secondary electrical network is greater than the voltage of the first secondary electrical network, thus making it possible to optimize the weight of the electrical architecture. The two secondary electrical networks may also be powered from autonomous sources of electricity as a replacement for the primary network to power the generator-starter and the electrical components.

Abstract: An architecture for a hybrid power plant for driving a rotorcraft rotor (1). The rotorcraft is fitted with an electrical energy distribution network (17) for distributing electrical energy from a management network (20) that is interposed between the distribution network (17) and electrical energy sources (4, 9, 10). A management computer (21) takes account of information about the working of a combustion engine (3) for driving the rotor (1), about the working of the electrical energy sources (4, 9, 10) fitted to the rotorcraft and including an energy store (9), a reversible electric machine (4), and an electricity generator (10) engaged with the combustion engine, and about the electrical energy needs of the electricity distribution network (17).
