PURPOSE: To make it possible to apply an electronic energy converter to various purposes in a wide range and improve its usefulness by composing it so that energy to be generated at the time of occurrence of surfacing current.

CONSTITUTION: A surface current generator 5 as a modulator is arranged so that it pierces through openings 8, 8' of cores 7, 7' of a pair of winding coils 6, 6' at the output side. Surfacing current wires 3, 4 are connected to a common low voltage winding 19 through low voltage wiring plates 17, 18 and the winding 19 is caused to oppose to a core 21 on which winding coils 20, 20' are wound around. A transformer is composed of a transformer unit 26 at the input side and another transformer unit 27 at the output side, and the output of the transformer unit 26 is applied to the surfacing current wires 3, 4 of the modulator 5 through wiring 18 as an input, and the electronic energy of the modulator 5 is converted at the output transformer unit 27 and it is taken out as an output voltage through winding coils 6, 6'. The conversion of energy itself is based on Biot Savart's law.
