Claim:
1. An electric energy conversion system, comprising a primary module and a secondary module, the primary module including two input terminals capable of receiving an electric current, a primary winding, and a primary capacitor connected to the primary winding and the input terminals, the secondary module including two output terminals, a secondary winding, and a secondary capacitor connected to the secondary winding and the output terminals, the primary winding being configured to induce a current in the secondary winding when the primary winding and the secondary winding are magnetically coupled and a current is received between the input terminals of the primary winding, wherein the secondary module further comprises a secondary switch electrically connected to the secondary capacitor and to the secondary winding, and circuitry configured to control the secondary switch, the secondary switch being able to switch, reversibly, between a first configuration in which the current induced in the secondary winding flows to the output terminals, and a second configuration in which said induced current flows in a closed loop through the secondary winding and the secondary capacitor without being delivered to the output terminals, when the primary module generates an electric pulse through the primary winding while the secondary switch is in the second configuration, the primary module is configured to detect presence of the secondary module by detecting a number of resonance frequencies of a current flowing in the primary winding.
