ELEKTRONISCHE HALBBRÜCKENVORRICHTUNG MIT ZWEI SYSTEMEN ZUR MINIMIERUNG DER STILLSTANDSZEIT ZWISCHEN DEN SCHALTOPERATIONEN EINES HOCHPEGELSCHALTERS UND EINES NIEDRIGPEGELSCHALTERS

摘要

The invention relates to a half-bridge electronic device (100) comprising a high level switch (2) and a low level switch (1) in series that are connected at a central point (3), the device (100) comprises a first (10) and a second (20) synchronisation system: • the first system (10) comprising a first detection circuit (11) configured to interpret a variation, following a falling edge, of the voltage (Vm) at the central point (3), and the first system (10) being configured to generate a first synchronisation signal (ATON- LS) for activating the low level switch (1); • the second system (20) comprising a second detection circuit (21) configured to interpret a variation, following a rising edge, of the voltage (Vm) at the central point (3), and the second system (20) being configured to generate a second synchronisation signal (ATON- HS) for activating the high level switch (2).
