Abstract:
1. An electric power supply source which is intended to be connected to an electric charge by means of a removable connecting cable, including: a controllable electric power conversion circuit which is used to convert an electric input signal into an electric output signal, at least one characteristic of said electric output signal being controllable; a control circuit for the controllable power conversion circuit which is used to control said at least one characteristic of the electric output signal according to a selection code that is representative of the requirements of the connected charge, characterized in that it includes a cable presence detection circuit capable of delivering a signal of absence of the connecting cable to the control circuit, and in that the control circuit is capable, in response to the signal of absence of the connecting cable, of controlling the power conversion circuit in order to obtain, at the output thereof, a same pre-determined quiescent value for said at least one characteristic of the output electric signal; said same pre-determined quiescent value being acceptable for all the electric charges liable to be connected to the power supply source.
