Zusammenfassung:A half-bridge electronic device comprises a high level switch and a low level switch in series that are connected at a central point, and a first and a second synchronization system: * the first system comprising a first detection circuit configured to interpret a variation, following a falling edge, of the voltage (Vm) at the central point, and the first system being configured to generate a first synchronization signal (ATON-LS) for activating the low level switch; * the second system comprising a second detection circuit configured to interpret a variation, following a rising edge, of the voltage (Vm) at the central point, and the second system being configured to generate a second synchronization signal (ATON-HS) for activating the high level switch.
