Abstract (en)

[origin: WO2019224451A1] The invention relates to a half-bridge electronic device (100) comprising, in series, a low level switch (1) and a high level switch (2) connected at a central point (3), and respectively controlled by a first (SLS) and a second (SHS) activation/deactivation signal. The device (100) comprises: • a first (10) and a second (20) synchronisation system configured to interpret a variation in the voltage (Vm) at the central point (3), respectively following a falling edge and following a rising edge, and to respectively generate a first (ATON-LS) and a second (ATON-HS) synchronisation signal separate from the first; • a first (18) and a second (28) AND type logic gate respectively combining the first synchronisation signal (ATON-LS) with a first control signal (PWM-LS) and the second synchronisation signal (ATON-HS) with a second control signal (PWM-HS), in order to respectively form the first (SLS) and second (SHS) activation/deactivation signals.
