Abstract
A rotorcraft having at least one turboshaft engine with an electric starter powered from the onboard network that makes use of a battery and of a discharge module made up of a plurality of discharge members connected in series. An electric circuit comprises a regulator device for regulating a main bidirectional DC-DC static converter connected in series with the discharge module. The regulator device maintains equivalence between the current of the electric circuit and the current of the onboard network, regardless of the mode of operation of the discharge module, and does so by monitoring the voltage of the discharge module and the voltage of the onboard network.
