Title (EN) HALF-BRIDGE DRIVER AND POWER CONVERSION SYSTEM WITH SUCH DRIVER
(FR) CIRCUIT D'ATTAQUE DEMI-PONT ET CONVERTISSEUR DE PUISSANCE EQUIPE DE CE CIRCUIT
Abstract: front page image
(EN)This invention relates to a half-bridge driver comprising first and second power switches, connected with their respective current paths in series, a pulse generator for generating a voltage pulse waveform, arranged to drive said first power switch (33), a first current generator (11), for generating a current pulse for each negative flank of said voltage pulse waveform, a second current generator (12), for generating a current pulse for each positive flank of said voltage pulse waveform, and a differential current receiver circuit (27), connected to said first and second current generators, and arranged to generate an output signal (I¿LATCH?) equal to the difference of the currents flowing through said current generators (11, 12), said output signal arranged to drive said second power switch (31).
(FR)La présente invention concerne un circuit d'attaque demi-pont à deux commutateurs de puissance aux passages de courant en série, un générateur d'impulsions produisant un signal en tension pulsé organisé pour attaquer le premier commutateur de puissance (33). Le premier générateur de courant (11) produit une impulsion en courant à chaque flanc négatif du signal en tension pulsé, et le second générateur de courant (12) à chaque flanc positif du signal pulsé en tension. Un circuit de réception de courant différentiel (27), aux bornes des deux générateurs de courant, est monté de façon à produire un signal de sortie (ILATCH) égal au différentiel de courants des générateurs de courant (11, 12), ce signal de sortie étant organisé pour attaquer le second commutateur de puissance (31).
