An electronic charger for electric power distribution installations is provided. The electronic charger includes a DC/DC converter of the SEPIC type including an input stage, an output stage and a coupling capacitor. The input stage is electrically connected with input terminals and includes an input inductor and a switching device. The output stage is electrically connected with output terminals and includes an output inductor, an output capacitor and a blocking device. The coupling capacitor is configured to electrically couple the input stage and the output stage with a capacitive coupling. A first sensor provides a first sensing signal indicative of a charging current. A first controller receives the first sensing signal and a reference signal and provides a driving signal to control the switching device.
