1. Electronic device comprising:
a first switch having a single voltage blocking direction;
a second switch, electrically in series with the first switch between a first node and a second node of application of a DC voltage;
a module configured to supply the second switch with a control signal, referenced to a potential of a third node corresponding to a midpoint between the first and second switches and comprising:
a first circuit for controlling the first switch, configured to receive a first square-pulse control signal, referenced to the potential of said third node;
a second circuit for controlling the second switch, configured to receive a second square-pulse control signal, referenced to the potential of said third node,
the first circuit comprising:
an assembly for shaping the first square-pulse control signal between a level of a first terminal for supplying a first positive potential positive with respect to said level of the second node and said second node, the assembly comprising an inverter amplifier;
a first diode between the input of the inverter amplifier and a second input terminal of the first circuit to which is applied the first square-pule control signal, the anode of the first diode being on a side of an input of the inverter amplifier; and
a first resistor between the first terminal and the input of the inverter amplifier; and
a controller and a field-effect transistor internal or external to said controller, connecting the cathode of the first diode to said third node, said field-effect transistor being controlled by a signal representing an inverse of the first square-pulse control signal.
